We're making this configuration:
Internal network 1 -- PIX 1 -- Internet -- PIX 2 -- Firewall -- Internal Network 2
We don't have problems configuring the VPN site to site, but the problem now is that we have to pass thru the firewall in fron of internal network 2.
What type of configuration could be use in that firewall?? Maybe to No-NAT packets from internal network??? Or change some configuration in PIX device?
In a simple topology without firewall, we're using the "Simple PIX-to-PIX VPN tunnel configuration Example" from this article:
The idea is to use the same configuration, but adding a firewall in one of the network.
Can you give me some advice to make this configuration?
Thanks in advance.
