Hi All,
I'm at a loss with this.
I need to get multipath source routing working in Trustix 2
Specifically, to get services on the Trustix box to respond to the
outside world from port forwards from 2 gateways.
I have done extensive searching on Google, and from what I can tell, the
following is required.
CONFIG_IP_ADVANCED_ROUTER
CONFIG_IP_MULTIPLE_TABLES
CONFIG_IP_ROUTE_MULTIPATH
These need to be enabled in the kernel. My /boot/config-2.4.28-11tr shows all
3 options enabled.
Here's my configs, i'm using an alias on the nic for the second ip.
Ip addr list
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:03:ff:22:7b:7f brd ff:ff:ff:ff:ff:ff
inet 192.168.20.238/24 brd 192.168.20.255 scope global eth0
inet 192.168.20.237/24 brd 192.168.20.255 scope global secondary
eth0
Route -n
192.168.20.0 0.0.0.0 255.255.255.0 U 0 0 0
eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0
lo
0.0.0.0 192.168.20.254 0.0.0.0 UG 0 0 0
eth0
ip rule
0: from all lookup local
32765: from 192.168.20.237 lookup 1
32766: from all lookup main
32767: from all lookup default
ip route list table 1
default via 192.168.20.252 dev eth0 src 192.168.20.237
Obviously, 192.168.20.254 is one gateway (default), and 192.168.20.252
is the other.
>From my understanding, this is all that's required. I shouldn't need an
iptables stuff or kernel flags.
I tried the same configuration on an old redhat 9 box and it worked.
Any ideas?
Thanks
Mark
