Since upgrading to 25.7.3 and _3 I've had nothing but issues with aliases and policy based routing. Also haivng my OPNVPN clients turned on acting as gateways kills external routing on my two vlans that potentially use them. If I turn off the OPNVPN clients routing returns. I've confirmed alsiases aren't working by plugging in the IP address of a machine I want VPN routed and the rule works.
Gateways
Fixing the alias issue corrected both problems. Hopefully this gets addressed.
