Hi
There is a Centos 7 up-to-date box with 2 interfaces, let's say 192.168.1.12 - enp2s0, 192.168.1.13 on enp3s0. Default gateway on enp2s0.
The gateway is pfsense, IP is 192.168.1.1 with 2 WAN connections
On the gateway the outgoing traffic is routed by source ip to different WAN, 192.168.1.12 to WAN1 and 192.168.1.13 to WAN2
On the centos box are set all the route and routing rules:
route-enp2s0: 192.168.1.0/24 dev enp2s0 src 192.168.1.12 table t2 default via 192.168.1.1 dev enp2s0 table t2
route-enp3s0: 192.168.1.0/24 dev enp3s0 src 192.168.1.13 table t3 default via 192.168.1.1 dev enp3s0 table t3
rule-enp2s0: from 192.168.1.12/32 table t2 to 192.168.1.12/32 table t2
rule-enp3s0: from 192.168.1.13/32 table t3 to 192.168.1.13/32 table t3
All work when I add #route add default gw 192.168.1.1 dev enp3s0
And that way I have :
# ip route show default via 192.168.1.1 dev enp3s0 default via 192.168.1.1 dev enp2s0 169.254.0.0/16 dev enp2s0 scope link metric 1002 169.254.0.0/16 dev enp3s0 scope link metric 1003 192.168.1.0/24 dev enp2s0 proto kernel scope link src 192.168.1.12 192.168.1.0/24 dev enp3s0 proto kernel scope link src 192.168.1.13
But how can I add achieve this only with ip route command ... without route? Can I add this in any config files (ex: route-enp2s0)?
Thanks
