Thanks for the Info. This is no different than my configuration listed below:

I gave you two different setup scenarios. I gave you one without NAT at all, and I gave you pointers to documents laying out a NAT setup. It appears you want to use the 2nd, so disreguard anything I said in the first config. (although if you didn't want NAT turned on for Eth0 just remove the 'ip nat outside' statement, and you'll be routing on Eth0 and NAT'ing on Fa0).
If you do want NAT on both interfaces, you don't want your public IPs on Ethernet0 in a NAT configuration setup. That will just NAT translate from 126.96.36.199/29 into 188.8.131.52/30 the way you have things setup. Most likely, you want Eth0 to have a different private IP range than Fa0 does for NAT on both.
Then you'll want to setup static 'ip nat' statements mapping the outside public IPs into private internal IPs.
