[PVE-User] Inter VRF traffic

[Cyrus]

Hello!,

I'm trying to make traffic work between VRFs passing through a an
external firewall (opnsense+frr) but traffic seems to be resolved
locally by the node, even though source/destination are on different
VRFs (and ultimately doesn't work):

root at pve-01:~/bin# ip route get 192.168.111.10
192.168.111.10 via 192.168.203.145 dev vrfbr_L01VPN01 src

   cache

   cache

North/South traffic works anytime destination is an external network.

North/South traffic fails if destination is the host or a network in
another VRF and traffic should be forwarded via an external firewall.

Any hints?, is something missing?
