I setup a linux box to work as a router/fw. It has 3 nw cards
which are connected to different networks. To connect to the
cisco router (provided by the ISP) we used a rfc1597 address
space.
^ ISP
|
---------
| Cisco |
---------
| 192.168.0.1
|
| 192.168.0.2
---------
| Linux | x.x.x.1
| |-------- other boxes x.x.x.2 .. 10

Other boxes (private addresses)
The x.x.x.x addresses are "official" addresses.
Problem is that a package originating on the Linux gw and going
to the Cisco has a src address of 192.168.0.2 which of course
is dropped. The Cisco cannot easily be re-configured.
Is there any sane way to force the src address of packages
originating on the linux gw to a particular interface?
The only (ugly) solution which works so far is to assign a routable
address to the cisco interface and use 192.168.0.2 as an
if alias.
Thanks for any help/ideas/pointers.
