[Herefordshire] Routing two subnets

[Chris Bond]

http://www.linuxforums.org/forum/ntopic25532.html seems to suggest you need
to fwd the packets using iptables as the default routing is not doing
nothing - not sure what lines need to be added in a two-subnets though.

Might have not made it clear I can route on the linux box perfectly its on a
remote machine that where the default gateway is set to route that segment
that it doesn't route via the linux box.

Already done that but still doesn't route the packets!  Iptables -L shows
default ACCEPT so its not that blocking it... aby more ideas?


I assume your network is laid out like somewhat like:

[Box A]<---Subnet 1-->[eth? "Linux Box" eth?]<--Subnet 2-->[Box B]

Starting with basics I'll assume your attempting to ping Box B from Box A.
The output from this would be useful, even more useful would be the packet
capture whilst your pinging Box B (using tcpdump or ethereal).  But to start
with if give us the output from the 'route' command on all the boxes (plus a
corresponding 'ifconfig' [Linux] or 'ipconfig /all' [Windows]) and we can
work from there.

Thanks
Mark
