Re: bridging over the internet?

Hi Gerd,

I do something similar to this, but both ethernets are uniquely
numbered, so it's just routing over the cipe tunnel, rather than
bridged.

<LAN A>----<Linux FW/GW>--- Internet ---<Linux FW/GW>----<LAN B>
                     \----CIPE Tunnel----/

LAN A is 10.1.*.*
LAN B is 10.2.*.*

I've used CIPE endpoints of 192.168.0.1 and 192.168.0.2

FW/GW A just has a route net 10.2.0.0/16 via 192.168.0.2
FW/GW B just has a route net 10.1.0.0/16 via 192.168.0.1

Cheers,

Mark
