I''m using a 2.6.20-15-ubuntu (shipped with feisty) kernel with
Julian''s patches applied and it''s my 3rd day with tc, ip,
ifconfig and
the rest ;).
Got 2 ADSL uplinks. What I need is an ability to manually configure
uplink usage, so nothing like bonding by default. Failover is meant to
be provided via a shell script at the next step. Here is my config:
=# no need for default route for now
ip rule add prio 50 table main
ip route del default table main
# table and default route for gt
ip rule add prio 201 from 101.64.106.28/30 table gt
ip route add default via 101.64.105.29 dev eth2 src 101.64.105.30
proto static table gt
ip route append prohibit default table gt metric 1 proto static
# table and default route for ut
ip rule add prio 202 from 192.168.1.0/30 table ut
ip route add default via 192.168.1.1 dev eth3 src 192.168.1.2 proto
static table ut
ip route append prohibit default table ut metric 1 proto static
# no interface specified
ip rule add prio 222 table 222
ip route add default table 222 proto static nexthop via 192.168.1.1
dev eth3 nexthop via 101.64.105.29 dev eth2
=
The prob is that in case I set
iptables -t nat -A POSTROUTING -o eth3 -j SNAT --to 192.168.1.2,
client machines can access inet w/o probs, while
iptables -t nat -A POSTROUTING -o eth2 -j SNAT --to 101.64.105.30
would lead to a non-functional connection.
Could anyone please give a hint on what am I doing so wrong?
TIA.
