I have a cisco router sitting between two different networks. One of them is at a different location and is connected to the main location via a point-to-point (T1). It connects to the main location to use the internet. The IP range at the remote location is 10.10.* and the local addresses are all 192.168.* -- we recently installed a firewall that doesn't care for 10.10.* addresses arriving on the LAN port and drops those packets. Sitting between the 192.168.* and the 10.10.* network is a cisco router and I'd like to enable a Static NAT with that router which will map 10.10.* addresses to 192.10.*. Unfortunately, I don't really speak "router" and I'm having a bit of trouble configuring the router. Below is the current configuration: -------- memory-size iomem 25 ip subnet-zero no ip domain-lookup ! ! interface FastEthernet0 ip address 192.168.0.210 255.255.255.0 ! interface Serial0 ip address 192.168.1.1 255.255.255.0 ! ip classless ip route 0.0.0.0 0.0.0.0 192.168.0.200 ip route 10.0.0.0 255.0.0.0 192.168.1.2 no ip http server ! ! --------- Serial0 is the "inside" interface, FastEthernet0 is the "outside" interface. Can anyone help with the config change?

Do you have a firewall or another router in front of FastEthernet0 (towards internet)? If it's an intelligent FW, simply add 10.10.* into that FW. Thanks.
