Hello folks: I am trying to set up a router machine to handle all my
network connections to the internet and my local network. I have five
interfaces in total, three to ISPs (two adsl and one cable) and two
interfaces to my local network one to a switch and one wireless card.
I have some of the routing working acceptibly but another portion I
cannot get working not matter what I've tried. The cable connection
comes in on eth1 and I'd like the output to go back out that interface
but it doesn't appear to work as advertised. I would also like the
two adsl connections to return packets to the interface they came in
on and have packets originating from the local machine and networks
load balance out the two adsl connections. Currently this doesn't
appear to be working either. It seems straight forward in the
lartc.txt and ip-cref documents but it doesn't seem to work all the
same. I would be very appreciative if someone can tell me what I am
doing wrong.
I will include my cobbled together policy routing script below. It's
messy now because of all the silly things I've tried to get it working
the way I'd like. The ip route outputs below show a third nexthop to
the 70.25.176.129 address but I only have that currently running as a
test of outputing to all three ISP connections.
