Hi all,
We use iptables to firewall nat our environment then route the users
through either our bonded T1's, or two DSL lines (on a round robin
assignment). The T1 and DSL modems plug into a 3com 3300 switch and
the 3 ports going out on the firewall also plug into this switch. The
firewall does the nat translation and decides who goes to which route
(DSL/T1).
We want to add in another T1 as well as two more DSL lines. The goal
is to have them work exactly the same as the current setup but
because we can not expand the hardware far enough to support one RJ45
nic per network line I'm wondering if I can use good old ethernet
card aliasing. That is setup an ethX alias (eth0:0, eth0:1) to
represent each outgoing network line DSL or T1. This would then feed
into the 3com and just go out via the 3 newly added DSL/T1 modems.
Thoughts? Is this feasible or even worth the effort?
