Hi,
I searched for similar posts, but could not find an example use case, so posting here.
I have opnsense with the following
- vtnet0 - ISP1
- vtnet1 - LAN
- vtnet2 - ISP2
ISP1 is the default gateway, and all machines in the LAN use send/receive using ISP1.
suppose the IPs are like this.
ISP1 is 1.1.1.1
ISP2 is 2.2.2.2
LAN is 192.168.0.1
test-machine is 3.3.3.3 ( outside ip)
I am using cilium bgp in k8s and announcing the load balancer ip to opnsense.
I can see the 10.101.101.0/32 - announced OK.
since 10.101.101.0/32 is in route in opnsense, if I do http/curl 10.101.101.0, i get nginx test page from opnsense and all machines in the lan.
i also have following forwarding done in opnsense.
1.1.1.1 80/443 -> 10.101.101.0 80/443
2.2.2.2 80/443 -> 10.101.101.0 80/443
from 3.3.3.3 if I do curl 1.1.1.1, i get the nginx OK.
from 3.3.3.3 if I do curl 2.2.2.2, i do not get the page.
what i see when I try to do curl 2.2.2.2 is
vtnet2(ISP2) -> 3.3.3.3.xxxx -> 2.2.2.2.80
vtnet1(LAN) -> 10.101.101.0.80 -> 3.3.3.3.xxxx
vtnet0(ISP1) -> 2.2.2.2.80 -> 3.3.3.3.xxxx
here 2.2.2.2 ( ip from isp2) is seen as trying to go out via isp1
how do I add route/policy such that when request is made to 2.2.2.2(ISP2), it is returned via ISP2 and not via ISP1.
Thanks
