Can someone help me please
An inside server (192.168.92.6) need to access to a remote network 192.168.31.0.
A VPN site to site is established between Pix outside (192.168.111.6) and Multitech Firewall (192.168.111.200).
Now my inside server should connect to the remote network with this IP 172.20.20.6. So I have to Nat my inside server IP (192.168.92.6) to 172.20.20.6.
The remote network should connect to inside network by the 172.20.20.6.
My problem is I can establish a connexion to my inside network from the remote network but I cannot establish connexion (tcp) from my inside network to the remote network.
The weird thing is I can ping from both network each other.
This is my config below
access-list Outside_1_cryptomap extended permit ip 172.20.20.0 255.255.255.0 192.168.31.0 255.255.255.0
