  question

  How a crowd outside could reach a server ServerA on vlanA.

  Hello

  Concerning Point 1, Yes if the roads required for networks connected inside the network is done on pix.

  Concerning Point 2, if the IP address that you use within the network is routable (public IP), the command you gave will work. The command indicates that when 10.10.1.10 inside the network host wants to go outside the network, use the same IP address. Because NAT does not occur, the actual address of the server presents itself as the visible address and the address of the host. So if the IP address you specify is not a public IP address, outside world can't access.

• Cannot ping inside the ASA from the inside interface

  Don't know what I did wrong... appreciate any help

  Here is the page layout

  laptop--> cisco 3750 switch--> ASA5505 firewall--> future VPN tunnel

  Laptop, switch interface VLAN and inside the ASA are all in the same subnet

  Switch and ASA have all interfaces local network VIRTUAL 52 (the subnet in question), except for the external interface

  -----------------

  This is the problem

  laptop getting ip addressing and def GW via DHCP from the firewall

  switch and FW can ping each other without problem

  FW can't ping, still gets the DHCP scope.

  Thank you

  Hello

  How did you setup?

  The laptop is connected to a port of the 3750 (VLAN 52).

  The connection between the 3750 and the SAA is a chest or a link L3?

  If the 3750 has a SVI belonging to VLAN52, you can ping from the correct PC? As well as the ASA?

• Network for access to the external interface inside

  Hey,.

  I have an ASA5520 7.2 (1) I have a few probs with - which is something I struggle with that.

  I'm trying to hit a website of a host on the inside network that is actually hosted internally, but decides the static NAT would focus on the external interface of the firewall.

  Now I can see the TCP built, translation occurring at a port on the external interface, this port high dialogue to one of the static electricity would be addresses on the external interface, then that's all. There are no more entries in my journal in regards to the connection and I get not syn on the internal web server is so the connection is not back in.

  IP address outside 222.x.x.9 255.255.255.248

  IP address inside 192.168.87.1 255.255.255.0

  access lists access... :-

  Everything works fine when creating a global internet address - just not when address from inside and dynamic PAT is performed to the original address.

  To my knowledge the ASA supports only hairpining on a VPN tunnel. The security apparatus does not allow traffic that is sent to an interface to go back in the direction of what she received.

• The number of packets of high-head ASA5510 inside Interface

  We have experienced some problems with occasional connections to VPN clients. In investgating, we used the mtr utility to draw LAN upside to an external host. First jump (from the host of the ASA) packet loss seemed excessive, sometimes up to 50%. The only thing between the host and the SAA is a gigabit switch. A flood of ping to the host even to the same destinations show a 0% packet loss.

  Looking at the inside interface, the use of the ASDM Interface Grapher for number packet Drop shows almost compatible 510-512 Kpackets lost.

  What are the causes of thie? Can it be mitigated by reconfiguring the Auto/Auto Interface to 1000/Full? Where can I start looking for the source of this decline in package, and is this real or some artifacts of the ASA firmware?

  I read somewhere that Cisco recommends that the connection between the switch and the firewall must be set to auto / auto.

  Here is a troubleshooting guide for the interface on the ASA errors:

  https://supportforums.Cisco.com/docs/doc-12439

  Accommodation inside the switch is healthy without error?

  Here is a troubleshooting guide for the VPN problems. Check to see if there is no error logs on the client when they connect.

  If the problem can be replicated check for the error on the SAA logs as well.

• Site to site VPN tunnel - cannot ping the second interface of the firewall peer inside2

  I have two ASA 5505 firewall each with a basic license: FWa and FWb. currently there is a VPN tunnel between them work. I added a second (inside2) interface to the firewall, FWb, but I can't ping firewall FWa, so that I can ping the inside interface of FWa.

  Hi odelaporte2,

  Is very probably the "access management" command is not applied in the second inside, only inside primary (see the race management) which will confirm.

  This command can be applied to an interface at a time, for example, if the law is now applied to the inside, it can not be applied to the inside2 at the same time.

  It may be useful

• VPN site-to-customer contact on the external interface

  Hello

  Thanks in advance,

  Network diagram

  Here's what you can do. On the SAA add a static host for the server route, but do point to the inside interface of the firewall.

  route inside 10.0.2.100 255.255.255.255 10.0.1.254

  The firewall knows that he has to get out of the e2 interface because it is directly connected.

  On the server, you will need a static route to the VPN Pool pointing on the firewall.

  route add 10.0.3.0 mask 255.255.255.0  10.0.2.254

  On the firewall, you also have to add a route for the VPN Pool.

  route inside 10.0.3.0 255.255.255.0 10.0.1.200

• Established but LAN-to-Lan tunnel can not ping to a host on the inside

  We have two cisco vpn concentrator (3005).

  Behind, we use 172.20.184.0/24 (remote desktop)

  We are starting to do a lan-to-lan tunnel, the tunnel establishes no problem.

  the only problem is that I can ping only the inside interface of the

  hub of central administration. I can't ping (or other

  on each subnet.

  On each side, you must make sure that all your hosts know that the road to the other network is by the local hub or using static routes on each host, or adding routing appropriate on any device is your default gateway.

• Use the Gigabit Interface as an interface of Interior with guarantee of 100

  I have a PIX 525 with two Gigabit interfaces, and I'm doing an internal interface with 100 security, 'nameif ethernet0 gb inside the security100' is the command that should work. I get this message:

  Aspirin (config) # nameif ethernet0 gb inside the security100

• Public and private IPs on the same Interface by using NAT Exemption/policy NAT

  I'm looking for some feedback on whether my thoughts on the installation program will run.

  Equipment: PIX 515E 6.2 (2)

  Scenario:

  The inside interface of the PIX will host 3 blocks of addresses IP - 24 public 2 blocks and 1 private/16 block. (All IP addresses have been replaced by dummy blocks.)

  Blocks of audiences:

  * 192.168.10.0/24

  * 192.168.20.0/24

  Block of private:

  * 10.50.0.0/16

  Traffic from the public 2/24 blocks should go through the firewall without address translation.

  The two blocs of the public will be able to receive connections initiated from the Internet.

  Public blocks will need to be able to send and receive traffic on a static VPN tunnel to our headquarters without subject to address translation

  Traffic leaving the sector private/16 block should be subjected to PAT before passing through the firewall.

  Private/block 16 will not receive incoming traffic from the Internet (other than responses to outbound connections initiated from within the private block).

  However, the private block will also have to be able to send and receive traffic on a static VPN tunnel to our headquarters * without * subject to address translation (i.e. hosts on our corporate network must be able to initiate connections to the private block and vice versa).

  The inside interface of the PIX will be connected to a Catalyst 3xxx series layer 3 switch, which will be responsible for routing all internal (so the PIX will never be routing of traffic on the interface, it was received).

  My ideas on how to implement are:

  * Use the exemption of NAT to exempt public address translation blocks. This will allow incoming and outgoing connections through the firewall.

  * Use the exemption of NAT to exempt the block private NAT when connecting to our head office on the VPN tunnel.

  * Use policy NAT w / PAT to translate the block private connecting to all other hosts.

  I have translated these thoughts in the following configuration snippet.

  Because the NAT exemption is processed before policy NAT in the evaluation of the NAT rules, I believe that this should allow the public IP blocks treat incoming/outgoing traffic without translation, while submitting the private translation block (except during handling of incoming/outgoing connections to our network of corporate office).

  Can someone confirm my assumptions about this?

  # ----------------------------------------------------------------------

  traffic of # which should be exempted from translation

  permit ip 192.168.10.0 access list nat_exempt 255.255.255.0 any

  nat_exempt 192.168.20.0 ip access list allow 255.255.255.0 any

  nat_exempt ip 10.50.0.0 access list allow 255.255.0.0 10.100.0.0/16

  traffic of # which should be the subject of translation

  policy_nat ip 10.50.0.0 access list allow 255.255.0.0 any

  # Suppose 192.168.5.1 is the address to use for PAT

  Global (outside) 1 192.168.5.1

  NAT (inside) 0-list of access nat_exempt

  NAT (inside) 1 access-list policy_nat

  # assumes that 192.168.10.7 is the IP address of the inside layer 3 switch

  Route inside 192.168.10.0 255.255.255.0 192.168.10.7 1

  Route inside 192.168.20.0 255.255.255.0 192.168.10.7 1

  Route inside 10.50.0.0 255.255.0.0 192.168.10.7 1

  #assume the following configuration sections appear elsewhere: static tunnel VPN, ACL, ifconfig, etc..

  # ----------------------------------------------------------------------

  Yes, this will work, even if you don't need political NAT for the 10.50.0.0 network. For PAT the 10.50.0.0 network when to anywhere (except via VPN) just do:

  Global 1 192.168.15.1 (outside)

  NAT (inside) 1 10.50.0.0 255.255.0.0

  As I said, you have works perfectly, the above is just an easier way to do it.

• WebVPN and anyconnect on the same interface

  Hello!!

  We have ASA 5520 firewall running with code.9.1 (2). We already have webvpn running on the firewall and has active users to use it. Now, the client came with a new requirement to configure firewalls on the same anyconnect. We have installed VPN more premium license.

  (1) is it possible to enable webvpn and anyconnect on the same interface. If Yes, what are the aspects we must consider to allow them both on the same interface?

  (2) how much webvpn and anyconnect vpn licenses should I do with my premium lincense?

  Please help on this.

  shver attached for reference.

  Best regards

  Sri

  Your peers licenses AnyConnect Premium gives you the right to access SSL VPN without customer and focused on the customer.

  Licensing is based on the concurrent users so regardless of the simultaneous dosing will work - as long as the number of connected does not exceed 100.

  Your site to site VPN IPsec does not count against this permission, but is rather against "Other peer VPNS" which does not require a separate license and is limited by the capacity of the ASA equipment (750 on your platform).

• Œuvres of VPn on the inside of the interface, but not outside

  I have a PIX-525 with UR license.  I tried to get my VPN to work since my iphone over the weekend, but nothing helped.  Then, I changed the interface inside to see if my iMac could connect and bingo!  It worked.  I then tried to log in via the inside of the interface with my iphone and it worked.

  I have connected a PIX-515e and, using the same settings, can connect to the external interface via my iPhone.

  Strange.

  Now, to answer the pressing questions, yes I changed the IP address of the server in my client IPSEC settings to reflect the external and internal interfaces I was testing each of them.  I was using a pré-partagées secret.  Yes, the secret has been entered correctly and they have all matched... Yes, the name of the tunnel has been entered correctly.  I used the database local user for authentication with username/password name (i.e. no certificate of authorization to make things simpler for debugging).  I changed the syslog to debugging and I see absolutely no error when you try to connect my iphone to the external interface (i.e. turn off wifi so I'm on my 3G data network).  The only thing I see is where my iphone hits the external interface and it's disassembly (or whatever his name is) but that's all.

  Why this work like a charm with my PIX-515e and not my PIX-525?  VPN accelerator card in the 525 can be at fault?  The 515e doesn't have the aecellerator card.  No idea why can't I several a VPN connection inside the interface but not outside?

  Hi Tim,.

  Well it's not so much the DNS rewrite that is the problem (if you delete just the keyword dns VPN will still fail) but using the external interface for NAT. So all traffic intended for your address of the external interface is passed to the "gcbrouter", including vpn traffic.

  I'm thinking about a way to solve this problem, but I really can't find anythign right now. Using a different interface will not work because you can have only a single default route.

  I wonder if this would work:

  remove the NAT interface:

  not static (DMZ, external) gcbrouter netmask 255.255.255.255 dns interface

  Replace with PAT interface, i.e. add such a line for each port that you want to be contactable on the DMZ server:

  static interface tcp 80 gcbrouter 80 netmask 255.255.255.255 (DMZ, outside) dns

  static (DMZ, outside) of the 25 gcbrouter 25 netmask 255.255.255.255 tcp interface dns

  etc.

  In all honesty, I have never seen rewriting dns used with PAT so not quite sure if it will work.

• VPN SSL from the inside on the external interface

  Hi all

  First of all I know that I can activate the SSL interface inside, but that's not what I need or want.

  Scenario:

  Several interfaces and VLAN on the SAA (running 8.0.5).

  SSL VPN configured and enabled on the external interface.

  Need to know if it is possible to access the SSL VPN from other interfaces directly to the IP address external interface, something like her hairpin.

  Possible a solution (if it exists) with or without NAT (I have public IPs on some interfaces).

  This will be useful for users who can connect any interface (inside, outside, or other) and with only a DNS record, I'll be able to manage everything.

  Concerning

  PS: Is DNS doctoring an option? The tests that I have done this does not work.

  In addition, you can consider setting the levels of security for the interfaces. They are all at 0. The value internal/private those a higher value.
