The mail.traffic table has a multipath route with diferent weights, I want
traffic to go by ISP1, but if it gets down, go by ISP2, but it is going out
by the ISP it get at random ..
ip route add table mail.traffic default nexthop via dev eth1 weight
1 nexthop via dev eth1 weight 200
ip rule add fwmark 0x02 table mail.traffic
iptables -A PREROUTING -t mangle -p tcp --dport 25 -j MARK --set-mark 0x02
iptables -A PREROUTING -t mangle -p tcp --dport 110 -j MARK --set-mark 0x02
Also I have other problem now .. on my multiroute (it is called that way)
table for the rest of traffic (the reverse order with weigths as on the
mail.traffic table), when GW1 gets down, traffic go out by GW2, thats ok ..
but when GW1 get online again traffic continues going by GW2, I have tryed
with "ip route flush cache", but it continues the same ... going out by GW2,
no matter the weights they have, no matter that GW1 is online again. Any way
to solve this ?
