Hi guys!
Im using FREEBSD box as my Linux gateway/fw. Now I want to have a multiple DSL
connection wherein our network can use it at the same time and should avoid
downtime once the other DSL connection is down. Could you show me the best docu
or tool/s on how to do this?
freebsd as ur linux gateway...ur one mixed-up dude linux win..hehehe
:-) just kidding..
anyways, if ur using freebsd, you can use pf (the *BSD firewall
implementation).
basically, u can't have two default gateways at the same time.
what you can do is provide for policy routing. like forcing all smtp
traffic through DSL1 then all http traffic through DSL2 somewhat
loadbalancing ur system. then u can do a little scripting (shell/perl)
that will monitor
ur current gateway (ping :-) ). If it's unreachable for a specific
period, ur script can then act accordingly, like changing the
/*defaultrouter */in ur rc.conf to ur 2nd DSL and editing ur pf.conf
i suggest you use two boxes for ur gateway to provide for hardware
redundancy.
hth. God bless!
