We are currently building two new servers as openbsd firewalls. During our testing, connectivity broke. We have disabled pf so it won't cause problems.
In our ping tests we found the packets aren't getting forwarded. ipforwarding is set to 1. When we ran netstat -r we found it takes forever, (more than ten minutes so far), to display the routes on the interfaces.
From both sides we can ping into the far side of the firewall but not any devices on the same net as the far side of the firewall.
Is there anyplace else where routing can get messed up? I'm reaching the point of doing a re-install but would like to know how this could happen.
