PIX Configuration problems

[one234]

Hello All,

I'm trying to configure a Cisco PIX so users can connect to the PIX using the Cisco VPN client and access the local network (1 subnet )

I think this should be 1 of the easiest configurations possible, but I’m unable to get it to work.

The network looks like this:

Outside ip address: 192.168.4.250 (For test, this is going to be a internet address)
Inside ip address: 192.168.2.1/24
DHCP pool: 192.168.3.100-192.168.3.109

Users are able to connect to the PIX using a pre-shared key and a username and password. They also get an IP address from the DHCP pool.

The problem is that users are unable to connect/ping to servers in the local LAN (192.168.2.x) and from the 2.x network to the 3.x network.

Could anyone tell me how to configure the PIX so users will be able to connect to the servers and apps on the 192.168.2.x network?

Thank you in advance!

Best regards,

Marc D.

Could you provide your config, I am thinking it has to do with your NAT transversal. I had this same problem about a year ago.

See if you have

sysopt connection permit-ipsec

in your config. This allows all IPsec traffic to bypass the outside interface ACL. Also, make sure that your ACL on the inside interface isn't blocking the traffic sent back out.

Try adding an outside route.
