I have a pix 501 firewall that I need to setup a site to site ipsec tunnel with a remote peer. The inside subnet on my pix is 192.168.100.0/24. For this discussion purpose, let's say my pix's outside ip is 10.10.10.10 and the remote peer ip is 188.8.131.52.
The tunnel needs are as follows: Local IP of 192.168.100.10 needs to communicate with remote ip of 184.108.40.206
I have to NAT my local ip of 192.168.100.10 to the ip address of 10.10.10.11 before it traverses the tunnel to the remote end.
I have setup the following, but I don't see any indication of phase 2. I see phase 1 completing, but nothing for encaps/decaps when I do a "show cry ipsec sa"
Here is the related config, minus the encryption parameters. please review and see if there are any issues with it, I'm particularly concerned about whether or not I'm NAT'ng correctly.
