General Discussion / bad forwarding decisions
« on: January 18, 2022, 04:10:41 pm »
i am trying to evaluate opnsense to replace 10G internet router, and the device is making strange forwarding decisions. I have a default route and one BGP peer, announcing one subnet. Traffic to this subnet works perfectly -- so i can ping out -- the problem is that when pinging from the other side of the bgp peer, the replies are sent to default gateway...
Please see attached screen shot showing the same src/dst pair- but different next hop MAC address
Local host on trusted side of OPNSense is 172.20.22.21 -- IP of host on other side of BGP-learned link 172.20.34.100
The most puzzling part, is that if i disable all firewall - it routes/forwards correctly.
please help, as i really want to use OPNSENSE as my 10G internet router.
