Question New Firewall Creation


I tried to create a new firewall by copying an existing pf.conf file to a brand new OpenBSD installation. But from my LAN internet is not accessible.

I try,

pfctl -nf /etc/pf.conf and it didn't give any errors

then I try,

pfctl -f /etc/pf.conf
and it gave the following error

pfctl: SIOCGIFMTU: Device not configured

My external interface card have Realtek chipset. Why this error occur? when I try to ping www.google.lk it pings but from my LAN internet is not accessible.
