Title: NAT on a third ethernet card
Post by: Sylvan on May 17, 2003, 01:19:49 AM

Did anyone try to use Mitel v.5.6 with two lease line hook to a quad-card ethernet P4 mail/files/web/fwll?

I really like Mitel Unsuported version, I have been in the Linux community mainly K-12 project developpement I have been reading the Developpement Forum List and need kind of help resolving our corporate Firewall deployment issue. I know I could use a IPcop or smoothwall IPchain packet filter router buuuuut I have so many contrib to take care I would use my expertise to find a way to pre-route and load balance between HA for fail-over and balance packet back and forth on our 10 and 30Mbits lease line and secure or replace our old RH6.1 Firewall IPchain and IProute2 contribs.

I did it before on E-Smith 4.1.2, there was a kernel patch that would allow you to load balance across two external interfaces.  Obviously there was no GUI for it, and /sbin/e-smith/console still only saw  one external interface, but using the command-line after recomiling my kernel I was able to NAT load balance across a cable modem and a DSL line.

Additionally, you can also load balance across "virtual" or "aliased" devices as well.  I'll have to see if I can dig up the patches, hopefully I stilll have that bookmark, this was at least one year ago.

Thanks,
Nathan

We are successfully using epipe serverware (www.ml-ip.com) on top
of a e-smith v5.6 to loadbalance and have failover of our 3 ADSL
lines. Support up to 6 outgoing lines. Cost $1000 but IMHO is worth
it, if your are not up to kernel magic.
