My network...

LAN B - 192.168.10.0 --> Server VPN OPENSWAN --> INTERNET --> ROUTER 2800 --> LAN A - 192.168.20.0

Need to do a DNAT that LAN A be able to connect on a specific port with a host at LAN B using the cisco router ip.

All info abou DNAT i could find was about PIX, any clues on IOS?

On the 2800 router

ip nat inside source static 192.168.10.10 2001 195.76.11.1 25

where 195.76.11.1 is the 2800 router interface and port 2001 is the port you want.
