• ASA at PIX VPN - routing

  Hi all, I built a site 2 site between an ASA 5510 and a PIX IPsec tunnel.  The tunnel is up, and most of the time the traffic flow between source and destination LANs as planned. The problem is that we need the ASA to send syslog messages in the VPN tunnel to a syslog on PIX site server.  If I get a router on the ASA website, I ping the site of PIX syslog server.   The following statement is in the ASA:

  Route out of pix.net.addr sub.net.mask next.hop

  But in the journal of the ASA, I see messages "Routing failed" for the traffic of the SAA on the syslog server.

  April 8, 2010 08:32:01 ASA5510: % ASA-6-110003: routing could not locate the next hop for icmp NP identity Ifc:10.xx.x.xx/0 to inside:172.xx.x.xx/0

  Any thoughts?

  Thank you

  Hello

  Public IP address of the ASA must be in interesting for this tunnel traffic (since it's the INVESTIGATION period where newspapers are going to be sent from).

  Also, the IP address of the syslog server must be in the interesting traffic.

  In other words, you should be able to PING from the ASA to syslog (through the tunnel) server.

• Between asa 5510 and router VPN

  Hello

  I configured ASA 5510 to vpn LAN to LAN with router 17 857. and between the routers.

  between vpn routers works very well.

  from the local network behind the ASA I can ping the computers behind routers.

  but computers behind routers, I cannot ping PSC behind ASA.

  I have configured the remote access with vpn cisco 4.X client, it works well with routers, but cannot work with asa.

  the asa is connected to the wan via zoom router (adsl)

  Are you telnet in the firewall?

  Follow these steps to display the debug output:

  monitor terminal

  farm forestry monitor 7 (type this config mode)

  Otherwise if its console, do "logging console 7'.

  can do

  Debug crypto ISAKMP

  Debug crypto ipsec

  and then generate a ping from one device to the back of the ASA having 192.168.200.0 address towards one of the VPN subnets... and then paste the result here

• ASA L2L IP WAN au Public

  Hi all

  I have an obligation to set up a private network virtual of our network for a developer with the following basic topology:

  Our private subnet - ASA (WAN IP) - VPN - end developer audience - protected Developer Public IPs point

  If the developer has a bunch of public IPs protected behind a single endpoint, so that we can have access, we have our external IP to establish a VPN to this endpoint.

  I understand that we will not use NAT as internal IP addresses will be PAT behind the external IP - traffic to the IPs developer audience then will bring up the VPN tunnel and everything works as expected (I think?)

  Hello

  You can have communication with the public IP to L2L tunnel stack... What you need is NAT/PAT at both ends and your statement of cryptomap should be with your NAT or PAT... instead of... private LAN address by looking at your config, it seems to be okay... I also hope that your LAN users only launch the right of movement?

  Because to get out, you can have a generic Pat... but when the other end accepts traffic be tone should have a dedicated static NAT or direct public IP of the servers to an end... or at least King of thing port forwarding, they should have done on their end... If both ends have a generic pat then it won't work.

• ASA encrypt interesting VPN traffic

  Hello everybody out there using ASA.

  I had a few IPSEC VPN tunnels between the company's central site and remote sites.

  Two dsl lines were connected to the ASA, one for VPN traffic and the other for the internet.

  The default gateway has been configured online internet, some static while insured roads as traffic to the sites of the company was sent through the other line.

  A few days ago we changed the configuration of ASA to use only a single dsl connection, then the line serving the internet has been cut, while the other will become the gateway default and static routes have been removed.

  The VPN connections instant stopped working and trying to send packets to the remote lan, it seems that ASA will not recognize that the traffic is encrypted. Obviousely we checked cryptomap, acl, ecc, but we find no problem... do you have any suggestions?

  Thanks in advance,

  Matt

  Hello

  Your exit the ASA must be encrypting the traffic between XNetwork and YNetwork.

  If the ASA does not encrypt this traffic, it could be because there is a problem with the NAT configuration.

  When the ASA receives a packet, it must first check if there are ACLs that allows traffic, passes through the inspection engine and check that the associated NAT. For example, if the package is coordinated, then the private IP encryption will never take place.

  Could ensure you that packets from the XNetwork are really reach the ASA, the NAT rule is correct and you may be looking for "debugging cry isa 127" and "scream ips 127" debug to check for errors of incompatibility.

  In addition, what is the condition of the tunnel trying to communicate: "sh cry isa his"

• Route VPN site to site on one path other than the default gateway

  I want to route VPN site-to-site on one path other than the default gateway

  ASA 5510

  OS 8.0 8.3 soon

  1 (surf) adsl line interface default gateway

  line 1 interface SDSL (10 VPN site-to-site)

  1 LAN interface

  What's possible?

  Thank you

  Sorry for my English

  Here is the assumption that I will do:

  -Your IP SHDL is 200.1.1.1, and the next hop is 200.1.1.2

  -Your LAN-to-LAN ends on this interface (interface card crypto SHDL)

  -VPN peer 1 - 150.1.1.1 and LAN is 192.168.1.0/24

  -VPN peer 2 - 175.1.1.1 and LAN is 192.168.5.0/24

  This is the routing based on the assumption above:

  Route SHDL 150.1.1.1 255.255.255.255 200.1.1.2

  Route SHDL 175.1.1.1 255.255.255.255 200.1.1.2

  Route SHDL 192.168.1.0 255.255.255.0 200.1.1.2

  Route SHDL 192.168.5.0 255.255.255.0 200.1.1.2

• Unusual routing VPN configuration

  Hi, I use a PIX 525 to our main site, and one of the remote sites using a router in 1721. The 1721 connects to the LAN. All traffic is forced to use a virtual private network between the remote sites and main. The intention was to force the internet traffic from the remote site through the filter of content on the main site, rather than use the split tunneling to leave straight out to the internet through their DSL connection.

  The problem is that, of course, internet traffic this VPN comes back the PIX, Internet. Our content filter reflects the way of the switch connected to the internal interface of a PIX.

  I need to find a way to route VPN traffic from the remote site to an ethernet on the PIX interface which will be connected to our switch stack. If I can do this without breaking the VPN, traffic should be filtered on the main façade and through VPN to the remote side.

  Yes, you're pretty much toast unless:

  you choose to configure a web proxy to Headquarters and set up remote PCs to use it. In this way, they use a proxy that is located behind the 8e6.

  Same pix os 7 will not help, as all nat occurs on this topic - just remote communication will flow through the pix, never hit its physical interface or internal switch ports inside and so the 8e6.

• ASA IPP on VPN L2L w/NAT

  I have a tunnel VPN L2L on a Cisco ASA 5520 I am trying to get IPPS, to work on. On my ACL cryptomap I defined a local group object and a remote object-group, and I'm the one-to-one NAT scene on the local group. I also have a configured route map that will take the static routes and redistribute in my ACE. EIGRP two things - 1, I noticed, I don't see on my ASA static routes that point to remote subnets and 2, the ACL that I used in my definition of route map is not getting any hits on it.

  Any thoughts on where I can go wrong?

  Thank you

  You have configured the following:

  crypto set reverse-road map

  If you do, can you remove and Add again and see if that fixes the problem?

  If your router acl is

  then your ASA acl should be

• Static and NAT router to router VPN

  Hello

  I have two site VPN using routers. The VPN is fine, BUT - at the end of the seat, the customer has NAT entries static to allow incoming connections - any service that has a NAT static to allow incoming connections from the Internet is inaccessible in the same way. Ping, for example, doesn't have this problem because there is no static NAT entry. I tried to configure a route map-"No. - nat" according to the http://www.cisco.com/en/US/partner/tech/tk583/tk372/technologies_configuration_example09186a00800949ef.shtml , I thought I was working.

  H.O. has the IP 131.203.64.0/24 and 135.0.0.0/24 (I know, I know - I'm trying to change), and the R.O. 192.168.1.0/24.

  Bits of configuration:

  IP nat inside source overload map route SHEEP interface Ethernet0

  IP nat inside source static tcp 135.0.0.248 131.203.100.27 3389 3389 extensible

  (other static removed)

  Int-E0-In extended IP access list

  ip permit 192.168.1.0 0.0.0.255 any

  (other entries deleted)

  access-list 198 deny ip 131.203.64.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 198 deny ip 135.0.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 198 allow ip 135.0.0.0 0.0.0.255 any

  SHEEP allowed 10 route map

  corresponds to the IP 198

  1 remove the static entry for the specified host the VPN problem, but obviously breaks things :(

  2. as mentioned, the VPN itself works fine, I can ping hosts perfectly.

  Any help greatly appreciated :)

  Thank you

  Mike.

  You must use the option of the route to the static NAT map. This is a new feature in 12.2 (4) T according to this page:

  http://www.Cisco.com/univercd/CC/TD/doc/product/software/ios123/123cgcr/ipras_r/ip1_i2g.htm#1079180

  He must do exactly what you want. The old, another way to do is use "The thing", where you create a loopback interface and don't make a nat interface and use routing strategy for routing VPN traffic to one address on the same subnet as the loopback interface, but not the address of the loop. IOS then that réacheminera traffic to the real destination (in this case the remote VPN site), but since now it is not a 'ip nat inside' interface, the static nat translations does not apply and the VPN traffic will not be translated. The problem with this solution is that all loopback traffic is switched to the process, so it is a bit of a hack, but these things are sometimes necessary.

• ASA 5520: Remote VPN Clients cannot ping LAN, Internet

  I've set up a few of them in my time, but I am confused with this one.  Can I establish connect via VPN tunnel but I can't ping or go on the internet.  I searched the forum for similar and found a little issues, but none of the fixes seem to match.  I noticed a strange thing is when I run ipconfig/all of the vpn client, the IP address that has been leased over the Pool of the VPN is also the default gateway!

  I have attached the config.  Help, please.

  Thank you!

  Exemption of NAT ACL has not yet been applied.

  NAT (inside) 0-list of access Inside_nat0_outbound

  In addition, you have not split tunnel, not sure you were using internet ASA for the vpn client internet browsing.

  You can also enable icmp inspection if you test in scathing:

  Policy-map global_policy
  class inspection_default

  inspect the icmp

• IOS router + VPN + ACS downloadable IP ACL

  I want to use the function "Downloadable IP ACL" 3825-router VPN (OI 12.4 T) in combination with a CBS.

  In many documents and discussions, I read that it is possible to use the DACLs on "devices Cisco IOS version 12.3 (8) T or higher.

  Authentication and authorization by the AEC works and the device gets some settings of the av-pair-feature.

  I have tried several things to apply the DACL as the use of av pairs or ACS "Downloadable IP ACL" function, but nothing works.

  In the debug log, I see that the av pair is transmitted to the device, but it is not used.

  --> Can you tell me, is it possible to use the DACLs on the IOS routers?

  --> How does it work? What can I change?

  --> Is there a good manual to apply it?

  Thanks for your help!

  Martin

  It would be useful to know the PURPOSE of what you're trying to do...

  AFAIR client config mode requires no ACL for filtering short tunnel split ACL... and I have no way to test right now.

  If you want to allow or not some clients access to certain subnets why not investigate tunneling ACL and vpn-filter in combination with ACS split will rather than for the DACL.
