First off. Fe0/1 is "ip nat outside", Fe0/0 is "ip nat inside" and Se0/1 isn't a nat interface on R1. On R2; I have Se0/1 which isn't a nat interface, Fe0/0 which is "ip nat inside" and Fe0/1 which is "ip nat outside".
My ISP has given me some IP addresses that are pointed at 188.8.131.52 and I normally just go through the motions of nat'ing them to Fe0/0. I have a situation where I need one of the IP addresses that my ISP has pointed to 184.108.40.206 to go to the 192.168.2.0/24 network. I have to put a webserver there. I can't figure this out. Any ideas?
