Cisco 5505 VPN Remote Access Problems

Hi Yall,

      I have setup remote access via ASDM and it seems like I am missing some NAT rules and or something because I cannot connect for the life of me. I am using Cisco VPN client Version 5.0.01 0600 and I am recieving error message Reason 412:The remote peer is no longer responding. I am testing the connection internally from the site, is this causing a loop and preventing me from connecting? Do I need to test it remotely?

Here is my config;

Re: Cisco 5505 VPN Remote Access Problems


First  observation I do not see clear is the  incomplete nonat exempt rule access-list inside_nat0_outbound extended permit ip any 255 and comparing it against your VPN Pool address  VPN_Pool mask , also your VLAN1 which is your inside interface LAN that  also routes for network is  also used for VPN Pool which  by the way is ok, but also opens doors for problems and sometimes could be painfull to troubleshoot.

Personally  if there is not a real good reason to use VPN network ID and inside Network ID  I recomend to keep networks separated usinng their own network ID . If your  inside LAN is , make your VPN pool something different , is one example.

Going  back to your possible problems I would re-design your logical network for VPN pool, should be fairly  easy to do:

remove a recreate Pool

no ip local pool VPN_Pool mask

create new one

ip local pool VPN_Pool mask

remove this acl  --> access-list inside_nat0_outbound extended permit ip any 255......

add new  exempt acl bellow

access-list inside_nat0_outbound extended permit ip

one statement you also need is to enable  NAT traversal

asa(config)#crypto isakmp nat-traversal 20

that's it prety much,  you should test RA  VPN  from the outside internet.

Great, Thanks. I will test it once I dig my way out tomorrow...

Re: Cisco 5505 VPN Remote Access Problems
