Hi I hope someone might be able to help me. I have setup a remote access VPN on an ASA 5520. The VPN client connects ok, accepts my username and password and then I am in. I get an allocated IP address of 172.16.1.1 from the local pool. The problem is that I cannot then ping the inside LAN which is 192.168.1.1. I've got isakmp nat traversal set to default which is 20. I've been looking at this all day and I think I've gone crossed eyed, a fresh pair of eyes are definitley required, so any help would be gratefully received. My config is

Did you try by enabling
same-security-traffic permit inter-interface ?
Thx

I would suggest that you modify this line and make the sequence number for the entry for the dynamic map higher than any other sequence number in the crypto map
crypto map mymap 1 ipsec-isakmp dynamic dmap
Give it a try and let us know if it helps.

When you try to ping ASA's interface this kind of traffic belongs to control-plane. This traffic is not managed by access-list. Try the command icmp permit any inside

Hi Richard ,
- we don't need access-list with RA connection , we have the dynamic map that acts as a template , so your crypto config :
crypto map mymap 1 ipsec-isakmp dynamic dmap
crypto map mymap 2 match address NONAT
crypto map mymap 2 set security-association lifetime seconds 28800
crypto map mymap 2 set security-association lifetime kilobytes 4608000
crypto map mymap interface outside
map with seq 1 is being binded to the dynamic map , now map 2 you are using the nonat access list as the encryption trigger for this map , so this should not be there as it encrypt traffic from the inside subnet to the pool .
please remove the second entry, then test if not working please provide a capture from the inside interface .
HTH
Mohammad.
