Firewall rule gateway change not routing correctly?
«

Hi all. Coming over from pf and setting up again.
I typically run VPN connections whilst maintaining my standard ISP gateway. I typically sort things out with policy routing.
The standard firewall rule on the LAN to route to the default gateway is all fine and works as expected.
When I manually change the gateway to forcibly be the WAN_DHCP (the correct IP also shows in the pulldown) then nothing routes out.
I also have the WAN_DHCP gateway set to default as well explicitly.
I have also looked at the NAT and don't see any issues there either.
I can't see this being a bug so I am doing something wrong and not picking it up.
Help? TY.
Kev.

I believe that this may be solved.
If the default LAN pass rule is set to "default" gateway then it seems to implicitly allow LAN-LAN traffic.
It appears that in this setup, my internal DNS server is accessible.
If I modify the default LAN pass rule and explicitly set the gateway to my ISP, then I must add a LAN-LAN pass rule above this rule as it seems suddenly LAN traffic is not allowed.
Is this by design or an oversight? It's not a bad thing to have the LAN-LAN rule but shouldn't it be there by default from the initial setup?
