Hi all,

a given network looks like this:

[ext. host] - [router] - [OPT1 | M0n0wall | LAN] - [int. host]

The router handels dial-in sessions for the int. host. Both ext. host
and the router have dynamic IP addresses.
At the moment the router has a NAT rule which redirects some ports to
the int. host. These packets arrive at the int. host with the source
address of the ext. host. Is there any way to change the source
address of these packets to either the internal address of the router
or to m0n0walls address of the OPT1 interface?

Thanks very much for your help,
Bernd Holzinger
