OK! Need a little advice with this one. I'm familiar with basic Cisco configs, but this is a new one for me. Copies of the configs for the 2 routers are attached, with IP ranges and usernames etc obscured with xxx's.

Current situation: 2 sites, site A and site B. Cisco 1841's at both ends.

Site A is Internet-connected, with a /29 range of xxx.25.27.26 - xxx.25.27.30. Only one IP (xxx.xxx.25.27.26) is currently in use, and there are several NAT rules in place for this IP. Local subnet is 192.168.16.x/24.

Site A is connected to site B via a private fibre link, via VLAN101. Site B's local subnet is 192.168.15.x/24.

The change required is this:

- Configure one of the (currently unused) public IP's - preferably xxx.25.27.27 -  on the router at Site 1 to NAT ports 25, 80 & 443 to a machines at site B - 192.168.15.1.

Sounds simple, no? Out of my league though. Any input would be greatly appreciated. If any additional information is required - just let me know.

As you already have the routing in place to 192.168.15.0/24 network you can add another "ip nat" to your existing list.
eg: ip nat inside source static tcp x.25.27.27 25 192.168.15.1 25 extendable
add extra for the other ports
add into Fa0_ACL_IN

Or have you tried this already ?
