• L2l VPN Access-list crypto-interesting

  Hi everyone, I have a question.

  I have ASA1 and ASA2 connected via a private cloud to intellectual property and two hosts behind each of the ASA.

  The tunnel is up, and I can ping to host1, which is behind ASA1 host2 which is behind ASA2 over the VPN tunnel.

  When I show crypto ipsec his on ASA2 I see

  #pkts program: 451, #pkts encrypt: 451, #pkts digest: 451

  #pkts decaps: 451, #pkts decrypt: 451, #pkts check: 451

  and they are multiplying, each ping I have sent to host1 host2. But when I do sh cryptointeresting access-list that defines my crypto interesting traffic on ASA2 I see not growing hits with each ping I send host1 who is behind ASA1.

  The question is whether I'm supposed to see crtyptointeresting access-list hits rising on ASA2, when I ping host2 to host1, which is on the other end behind ASA1 (behind ASA2).

  Thank you

  Hi my friend.

  When you ping with the ASA2 ASA1 you won't see hitcounts in the ASA2 ACL. This happens because the number of access number to increase traffic must be defined in the ACL.

  Basically when you ping ASA1 with the ASA2 traffic does not match the direction of the ACL on ASA 2 crypto (which is defined from ASA2 LAN to LAN ASA1) so it does not count as a success.

  You see decrypted packets and decapsualated because the traffic corresponding to the terms previously negotiated for the VPN Tunnel, then the traffic gets encryped and sent through the tunnel.

  I hope this clarifies your questions.

  BTW sorry I did not get back to you on your second post NAT, I see that Varun has given you a great answer.

  Have fun!

• Routing VPN access list

  Hello

  I have a PIX 525 to my main site and a 1721 router at a remote location. I used the PDM and the SDM to configure site-to-site IPSec VPN connection. In my private network, I use 10.1.0.0/16 for the main site and 10.x.0.0/16 (where x = 2-47) to remote sites.

  The remote site with the VPN connection uses 10.19.0.0/16. When I originally created this VPN, I configured the traffic to flow from the remote site to 10.1.0.0/16 only. This means that the remote site cannot speak to any other remote sites, just the main site.

  I need to modify the access list to solve this problem. The relevant part of the remote site access list is now:

  access-list 103 allow ip 10.1.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 deny ip 10.19.0.0 0.0.255.255 everything

  Can I change the subnet mask in the first line and put the second line first?

  access-list 103 deny ip 10.19.0.0 0.0.255.255 everything

  access-list 103 allow ip 10.0.0.0 0.255.255.255 10.19.0.0 0.0.255.255

  Or should I let the deny at the end statement, and add a line for each of the other remote sites:

  access-list 103 allow ip 10.1.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 allow ip 10.2.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 allow ip 10.3.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  access-list 103 allow ip 10.4.0.0 0.0.255.255 10.19.0.0 0.0.255.255

  ... (others)

  access-list 103 deny ip 10.19.0.0 0.0.255.255 everything

  Thank you.

  Help the additional configuration information that you have posted. There are still a few things which I hope could be clarified. It seems that you have 46 remote sites and only is connected via a VPN. How have the other connectivity? It is all over the links within your private network? Is there than any NAT involved in these other connections?

  In my previous answer, I assumed that there will be multiple VPN connections, revealing your additional information is not the case. So my comment about limitations in PIX for talk of talks is true but not applicable to your situation.

  Other remote sites are also coming via the VPN? If yes access list 100 which the 1721 uses to identify the IPSec traffic (and that was not in your posted material) will probably have to be changed.

  According to access list 103 is concerned, I guess that the deny ip 10.19.0.0 0.0.255.255 is an anti-spoofing measure? If so, I would probably advocate put it as the first entry in the access list. What about if you want to use ip 10.0.0.0 allow 0.255.255.255 10.19.0.0 0.0.255.255 or a series of individual licenses, according to me, a point to consider is that allowed 10.0.0.0 0.255.255.255 will allow any space of 10 addresses. It seems that you use 1 to 47. What happens if something came through 10.122.x.x? I suggest a compromise approach. You can use this:

  IP 10.0.0.0 allow 0.31.255.255 10.19.0.0 0.0.255.255

  ip licensing 10.32.0.0 0.15.255.255 10.19.0.0 0.0.255.255

  This would allow 1 to 47 but not others.

• Capture packets for VPN traffic

  Hi team,

  Please help me to set the ACL and capture for remote access VPN traffic.

  To see the amount of traffic flows from this IP Source address.

  Source: Remote VPN IP (syringe) 10.10.10.10 access

  Destination: any

  That's what I've done does not

  extended VPN permit tcp host 10.10.10.10 access list all

  interface captures CAP_VPN VPN access to OUTSIDE gross-list data type

  Hello

  If you have configured capture with this access list, you filter all TCP traffic, so you will not be able to see the UDP or ICMP traffic too, I would recommend using the ACL, although only with intellectual property:

  list of allowed extended VPN ip host 10.10.10.10 access everything

  Capture interface outside access, VPN CAP_VPN-list

  Then with:

  See the capture of CAP_VPN

  You will be able to see the packet capture on the SAA, you can export the capture of a sniffer of packages as follows:

    https:// /capture//pcap capname--> CAP

  For more details of capture you can find it on this link

  Let me know if you could get the information that you were trying to achieve.

  Please Don t forget to rate and score as correct the helpful post!

• Lock the AnyConnect VPN with broader access list

  I'm trying to lock my AnyConnect VPN interface. I use the split tunneling. I want only to http tunnel traffic to an external http server we have and ftp to another external server behave. I don't want anything else through the tunnel or anywhere else allowed on our network. My current setup, I can connect to the vpn and the servers ping external ip address, but not by name. I can also not navigate anywhere else while I'm connected. It is not imperative for me to navigate anywhere else, when you are connected, but I need to allow only access specified above.

  Configuration:

• IOS VPN on 7200 12.3.1 and access-list problem

  I'm in IOS 12.3 (1) a 7200 and have configured it for VPN access. I use the Cisco VPN client. Wonder if someone has encountered the following problem, and if there is a fix.

  The external interface has the access-list standard applied that blocks incoming traffic. One of the rules is to block the IPs private, not routable, such as the 10.0.0.0 concern, for example.

  When I set my VPN connection, none of my packets get routed and I noticed that outside access list interface blocks the traffic. When I connect to the router through VPN, the router attributes to the client an IP address from a pool of the VPN as 10.1.1.0/24. But normal outside the access list denies this traffic as it should. But as soon as I have established a VPN connect, it seems that my encrypted VPN traffic must ignore the external interface access list.

  If I change my external access list to allow traffic from source address 10.1.1.0/24 my VPN traffic goes through correctly, but this goes against the application to have an outdoor access list that denies such traffic and have a VPN.

  Anyone else seen this problem or can recommend a software patch or version of IOS which works correctly?

  Thank you

  R

  That's how IOS has always worked, no way around it.

  The reasoning is to do with the internal routing on the router. Basically an encrypted packet inherits from the interface and initially past control of ACL as an encrypted packet. Then expelled the crypto engine and decrypted, so we now have this sitting pouch in the cryptographic engine part of the router. What do we with her now, keeping in mind users may want political route she is also, might want to exercise, qos, etc. etc. For this reason, the package is basically delivered on the external interface and running through everything, once again, this time as a decrypted packet. If the package hits the ACL twice, once encrypted and clear once.

  Your external ACL shall include the non encrypted and encrypted form of the package.

  Now, if you're afraid that people can then simply spoof packets to come from 10.1.1.0 and they will be allowed through your router, bzzzt, wrong. The first thing that the router checks when it receives a packet on an interface with a card encryption applied is that if the package needs to be encrypted, it is from his crypto ACL and its IP pools. If he receives a decrypted packet when it knows that it must have been encrypted, it will drop the package immediately and a flag a syslog something as "received the decrypted packet when it should have been."

  You can check on the old bug on this here:

  http://www.Cisco.com/cgi-bin/support/Bugtool/onebug.pl?BugID=CSCdz54626&submit=search

  and take note of the section of the security implications, you may need to slightly modify your configuration.

• Different 'outside_cryptomap access-list"for each VPN?

  Hello

  Just for my understanding.

  I have a VPN connected to my Cisco ASA 5520 when I tried to add an another VPN, the I must create a 2nd cryptomap, can I not create a group so there is only one card encryption?

  Currently I have:

  access-list 1 permit line outside_cryptomap_1 extended ip 0.0.0.0 0.0.0.0 172.19.15.0 255.255.255.0

  I just added outside_cryptomap_2 line access-list 1 permit extended ip 0.0.0.0 0.0.0.0 172.19.2.0 255.255.255.0

  But I was wondering if I could use something like:

  access-list 1 permit line outside_mycryptomap extended ip 0.0.0.0 0.0.0.0 VPN_Remote_Networks object-group

  When I do this, but I guess that this will cause a problem with the address in hand?

  You must use different access-list in cryptomap for each VPN.

• Access lists applied inbound VPN connections

  I try to configure access to homeland security lists, we have a multi site VPN services Terminal Server is the main traffic flowing on the VPN.

  102 of the ACL applies to cryptographic cards

  access-list 100 permit ip 10.1.5.0 255.255.255.0 10.1.6.0 255.255.255.0

  access-list 102 permit ip 10.1.5.0 255.255.255.0 10.1.6.0 255.255.255.0

  We need only allow traffic to domain connections and Terminal Server services only.

  I tried with no luck, remote clients lose the ability to auth against the domain controller.

  access-list 102 permit ip 10.1.5.20 host 10.1.6.0 255.255.255.0

  (DC also DNS and WINS)

  access-list 102 permit ip 10.1.5.21 host 10.1.6.0 255.255.255.0

  (DC secondary also DNS and WINS)

  access-list 102 permit ip 10.1.5.22 host 10.1.6.0 255.255.255.0

  access-list 102 permit ip 10.1.5.24 host 10.1.6.0 255.255.255.0

  (terminal server 3)

  If once they have connected to this topic, I've implemented these access lists it works very well, but once they log off and attempt to relog on, they are blocked. This leads me to believe there is more for field connections then meets the eye.

  Anyone have any suggestions for me? Everyone knows about this problem?

  Thanks in advance!

  Gregg

  Domain logon may require programming. It will probably be in the form of emissions e.g. directed 10.1.5.255. These emissions are going to spend your first list, but blocked by the second access list. To get around this, you can use assistance on the net 10.1.6.0 ip addresses. You can also add the following line to list 102:

  access-list 102 permit ip 10.1.5.255 host 10.1.6.0 255.255.255.0.

  Another thing to consider is to simplify your ACL 102. Small access lists provide better performance. In the given situation, the separate lines for 10.1.5.20 up to 10.1.5.23 IP addresses can be replaced by a oneliner: access-list 102 permit ip 10.1.5.20 255.255.255.252. Taking this one step further, you can even create a oneline for guests access list when you move the third server terminal server to the range of 16-19.

• Question of access list for Cisco 1710 performing the 3DES VPN tunnel

  I have a question about the use of access lists in the configuration of a router Cisco 1710 that uses access lists to control traffic through the VPN tunnel.

  For example the following lines in a configuration on the remote router. My question is whether or not the traffic that matches the definition of list access-130 (something other than 192.168.100.0/24), cross the VPN tunnel or go directly to the Ethernet0 interface.

  My understanding is that traffic that matches the access list 120 would be encrypted and sent through the IPSec tunnel. If there was "ban" set out in the statements of 120 access-list, the traffic for those would be sent through the IPSec tunnel but not encrypted (if possible). And finally, given that the definition of crypto card reference only "adapt to 120", any traffic that matches 130 access list would be sent Ethernet0 but not associated with the card encryption and thus not sent through the IPSec tunnel. "

  Any input or assistance would be greatly appreciated.

• ASA 5505: VPN access to different subnets

  Hi All-

  I'm trying to understand how to configure our ASA so that remote users can have VPN access to two different subnets (Office LAN and LAN phone).  Currently I have 3 VLAN configuration - VLAN 1 (inside), VLAN 2 (outside), VLAN 13 (phone LAN).  Essentially, remote users must be able to access their PC (192.168.1.0/24) and also have access to the office phone system (192.168.254.0/24).  Is it still possible?  Here are the configurations on our ASA,

  Hello

  Loss of connectivity to the LAN is not really supposed all remove this command UNLESS your network is using another device as their gateway to the Internet. In this case configuration dynamic PAT or political dynamics PAT (as you) would make sense because the LAN hosts would see your VPN connection from the same directly connected network users and would be know to traffic before the ASA rather than their default gateway.

  So is this just for VPN usage and NOT the gateway on the LAN?

  If it is just the VPN device I'd adding this

  global interface (phones) 10

  He would do the same translation for 'phones' as he does on 'inside' (of course with different PAT IP)

• Rule of NAT for vpn access... ?

  Hey, putting in place the vpn ssl via the client Anyconnect on a new ASA 5510, ASA ASDM 6.4.5 8.4.2.

  I am able to 'connect' through the anyconnect client, & I am assigned an ip address from the pool of vpn that I created, but I can't ping or you connect to internal servers.

  I think that I have configured the split tunneling ok following the guide below, I can browse the web nice & quickly while connected to the vpn but just can't find anything whatsoever on the internal network.

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080975e83.shtml

  I suspect her stockings for a nat rule, but I am a bit stuck if it should be a rule of nat object network or if it must be dynamic/static & if its between the external interface or external ip & network inside or the VPN (I created the pool on a different subnet), or a 'Beach' (but then I am getting overlapping ip errors when I try to create a rule for a range of IP addresses.

  Any advice appreciated,

  Hi Eunson,

  After have connected you to the ASA that clients receive an IP address, let's say 192.168.10.0/24 pool, the network behind the ASA is 192.168.20.0/24.

  On the SAA, you would need an NAT exemption for 192.168.20.0 to 192.168.10.0

  Create two groups of objects, for pool VPN and your itnernal LAN.

  object-group network object - 192.168.20.0

  object-network 192.168.20.0 255.255.255.0

  object-group network object - 192.168.10.0

  object-network 192.168.10.0 255.255.255.0

  NAT (inside, outside) 1 source static object - 192.168.20.0 object - 192.168.20.0 destination static object - 192.168.10.0 object - 192.168.10.0 non-proxy-arp-search to itinerary

  At the inside = interface behind which is your LOCAL lan

  Outside = the interface on which the Clients connect.

  If you can't still access then you can take the shot on the inside interface,

  create and acl

  access-list allowed test123 ip host x.x.x.x y.y.y.y host

  access-list allowed test123 ip host host x.x.x.x y.y.y.y

  interface test123 captures inside test123 access list

  view Cape test123

  It will show if the packages are extinguished inside the interface and if we see that the answers or not. If we have all the answers, this means that there might be a routing on the internal LAN problem as devices know may not be not to carry the traffic of 192.168.10.0 return to the ASA inside the interface.

  Or maybe it's that there is a firewall drop packets on your internal LAN.

• Ipv6 access list does not apply autonomous Aironet 3602I-E

  As you can see in the attached config I configured two SSID (2G & 5 G) for a third (2G only) SSID and PEAP WPA2-Ent on the vlan 2 for 'poor team access as guest '.

  Basically I forced the Dot11Radio0.2 interface in the Group of deck 1 to get all three SSIDS on vlan 1 (since I want just a quick way and dirty to allow its customers access to the internet, without having to configure a vlan separate everywhere).

  The guest SSID (XX COMMENTS) allows tkip in addition to BSE and uses a PSK rather than PEAP. Access lists configured on Dot11Radio0.2 IPv4 allows clients connected to this SSID get an IP by DHCP, use the DNS servers on the local network and access the internet. All other traffic for the local network is blocked by access lists guest_ingress and guest_egress.

  This all works very well, ipv4 is blocked for guests invited as expected. However, ipv6 is something different. For some reason, the ipv6 access list is completely ignored.

  Because I don't need ipv6 for guest access, I thought that I have completely block and do with it. As you can see I have this set:

  interface Dot11Radio0.2
  guest_ingress6 filter IPv6 traffic in
  guest_egress6 filter IPv6 traffic on

  and these ipv6 access lists have a rule of "refuse a whole" only. Yet, the XX COMMENTS SSID connected client gets an ipv6 address of the server on the LAN DHCP6 and has full connectivity. For ipv4, that I had to explicitly allow DHCP packets to the client not even get an IP, so the ipv6 access lists are not clearly applied.

  No matter if I move the access interface Dot11Radio0 instead lists, they don't do anything. I thought that maybe I should add a "enable ipv6" on the Dot11Radio0.2 interface (even if ipv6 traffic was very good, even where it shouldn't), but when I set "enable ipv6" Dot11Radio0 or Dot11Radio0.2 the radio goes into a sort of infinite loop of reset:

  000261: Sep 23 2016 22:32:50.512 it IS: % DOT11-5-EXPECTED_RADIO_RESET: restart Radio Dot11Radio0 interface due to the reset of the interface
  000262: Sep 23 2016 22:32:50.516 it IS: % LINK-6-UPDOWN: Interface Dot11Radio0, changed State to down
  000263: Sep 23 2016 22:32:50.524 it IS: % LINK-5-CHANGED: Interface Dot11Radio0, changed State to reset
  000264: Sep 23 2016 22:32:51.516 it IS: % LINEPROTO-5-UPDOWN: Line protocol on the Interface Dot11Radio0, state change downstairs

  000269: Sep 23 2016 22:32:53.608 it IS: % LINEPROTO-5-UPDOWN: Line protocol on Interface Dot11Radio0, changed State to
  000270: 22:32:53.608 Sep 23, 2016 it IS: % DOT11-5-EXPECTED_RADIO_RESET: restart Radio Dot11Radio0 interface due to the reset of the interface
  000271: Sep 23 2016 22:32:53.612 it IS: % LINK-6-UPDOWN: Interface Dot11Radio0, changed State to down
  etc.

  In addition, when creating a list like this ipv6 access:

  guest_egress6 IPv6 access list
  refuse an entire ipv6

  The other is automatically created:

  IPv6-guest_egress6 role-based access list
  refuse an entire ipv6

  A deletion also removes the other.

  What is happening with these ipv6 ACLs, why they are not blocking all traffic? Why do I get an acl "role-based" too? Is associated it with?

  Is there a another way to kill just any ipv6 on the SSID of COMMENTS XX traffic while leaving alone on others? That's all I need at this stage. If the ipv6 ACL do not work, perhaps this can be done (ab) using a service-policy or policy routing? I'm ready to creative solutions :)

  PS. I know this is not the recommended method to configure a guest SSID, but it should still work IMO.

  You have encountered a bug I discovered a few months ago (CSCva17063), in your case, the workaround is to apply the ACL on the physical rather than the void interface interface (because you want to completely block IPv6 in any case). I write (more) my conclusions regarding the traffic that refusal on autonomous APs in a blogpost, might be interesting for you to read as well.

  Remember that the access point used as a bridge between the wired infrastructure and wireless, not as a router. There's some IOS routing of commands (like the "enable IPv6" command you pointed out) , but these are not the characteristics that should be used or need to be enabled on an access point.

  Because the networks internal and customer spend somewhere else, I would perform filtering on this device instead. Also sub gi0.2 interface is missing from your configuration, so I do not think that access as a guest is currently working at all?

  Please rate helpful messages... :-)

• Access-list group policy and IPSec tunnel.

  I have an IPSec Site to Site VPN tunnel that ends on the external interface of the firewall. My ftp server is located in a demilitarized zone. The DMZ has an access list applied to the interface. When I created the Group of the tunnel for the Site to Site, I create a group of tunnel with group policy and manage the policy with filters. The filter looks like an access list. Are the filter and the ACL interface work together? The one replace the other? How they work together.

  Once traffic ipsec, acl interface is not used until you have enabled "sysopt conn allowed-/ ipsec vpn. When you add a vpn-filter, it is what will filter the ipsec traffic.

• ACL ASA5540 does not not for VPN access.

  I'm under code 8,03 and have a simple VPN L2L configured between two sites. It is in fact a test config in my lab, but I'm unable to restrict traffic using an ACL inside.

  I used the VPN Wizard to do the config initial and then added an Interior (out) ACL to restrict traffic once the tunnel rises.

  The encryption card is as follows:

  access extensive list ip 164.72.1.128 outside_1_cryptomap allow 255.255.255.240 host SunMed_pc

  Then I have an ACL to limit traffic to ping GHC_laptop, telnet to GHC_switch and denying the rest:

  inside_access_out list extended access allowed icmp host host SunMed_pc GHC_Laptop

  inside_access_out list extended access permit tcp host SunMed_pc host GHC_switch eq telnet

  inside_access_out deny ip extended access list a whole

  However SunMed_pc can also ping at GHC_switch and can FTP to GHC_laptop even if the 3rd entrance to deny any meter increases when I do this.

  I have attached a Word document that has the entire config with a screenshot showing the ACL and the shots.

  Should I configured incorrectly, or is ACL ACL actually does not work as expected?

  You can still keep all the IP for your acl interesting traffic. If you delete the sysopt, then you would write access in your acl 'inside_access' like you did above.

  If you are going to have dozens of tunnels l2l and will limit all, then I just remove the sysopt and use the acl interface.

  There is another option. You can leave the sysopt and use a vpn-filter. It is explained here and can be applied to l2l.

• (Browser) clientless SSL VPN access is not allowed.

  I'm trying to set up an additional Anyconnect vpn profile.  I have one that is working properly but this news will not.  When I try to log in to download the client or try to connect with a computer that already has the customer I can not.

  After reviewing the config, the difference between groups Anyconnect and SSL-RDP-Only is the AAA server.

  AnyConnect group uses the radius for authentication (RAS01) server, while the SSL-RDP-Only group uses an LDAP server for authentication (FUN-LDAP), and the configuration of the FUN-LDAP server, you configure the mapping of LDAP attributes, which is to map the group "An1meR0xs".

  To test, change authentication LDAP aaa RADIUS for the newly created group.

  Hope that helps.
