Hi!
I had two uplinks till today. We stopped one of them today, so i thought i could share my experience. (it is maybe useful for somebody)
I hadn't managed to configure it using a LARTC howto, but the Nano-howto (http://www.ssi.bg/~ja/nano.txt) and julian's kernel patches.
I had some problems with icq connections, because it is a two step connection (It is just theory).
1. Client --> Main server
2. Main Server --> Client ; Main server -> small server
3. Client -> small server
The problem is, when connection 1. use different uplink then connection 2.
Those icq related rules below corrected the problem.
My script: IF0=eth2 IF1=eth1 IF2=eth3 IF3=eth0 P0_NET=192.168.1.0/24 P1_NET=public1 P2_NET=public2
IP0=192.168.1.254 IP1=publicip1 IP2=publicip1
#gateway P1=publicgw1 P2=publicgw2
#table T1=211 T2=212 T3=222
IP=/sbin/ip
# Delete everything #$IP route flush cache $IP route flush all $IP route flush all table $T1 $IP route flush all table $T2 $IP route flush all table $T3
