How can I add a Remote Access VPN Connection on a PIX for a user to access their network from home when the PIX already has a VPN to VPN Tunnel to another Network.

You just need to add a few commands.
Please see this general example:
Some more examples depending of witch option you'll require

below are the sample codes for configuring both lan-lan vpn and remote vpn access on a single pix:

The problem I'm having is there already is an established VPN to VPN Tunnel there along with two nat (inside) and three access-lists...I'm trying to add a remote VPN to that and I'm struggling. I could post the config and let you guys look at it.
03-12-2006 09:18 PM
please do so then. with public ip masked.

Will this work for a User to access the network from home, right? I have to change the username and passwords and it should work. The only thing I see that I have a question on is the isakmp on yours is almost exactly what I have except for the encryption,
my line: isakmp policy 10 encryption aes-256
your line:isakmp policy 10 encryption aes
what is the correct one? the rest is the same.
03-14-2006 06:00 AM
Ok I added the commands that you have suggested except for the following:
isakmp policy 10 authentication pre-share
isakmp policy 10 encryption aes
isakmp policy 10 hash sha
isakmp policy 10 group 2
isakmp policy 10 lifetime 86400
I have these already in the config except the aes is different. I setup the VPN Client to try it and it does not connect.
03-14-2006 12:27 PM
I entered the following commands above and it is not working it drops the VPN Session. I'm not sure what the issue could be.
03-14-2006 06:39 PM
the matter is the "isakmp policy xx group 2". vpn client needs group 2, and the one in the current config is group 5.
03-14-2006 07:37 PM
I have tried the command with that policy group but it didn't work. What does that VPN Client settings have to be? and what does group 5 used for?
03-14-2006 10:06 PM
please post the entire config with the new codes for remote vpn access, and with public ip masked.
