Maybe use wm0 as the external interface.

If you are useing pppoe(4) to connect to the ISP then you may want to
set the MTU of the ethernet device to 1508 so that you get an MTU of
1500 on the pppoe tunnel.

In /etc/ppp/ip-up I have:

#! /bin/sh
/sbin/route add default $5

/etc/ppp/ip-down is:

#! /bin/sh
/sbin/route delete default $5


I do have one extra line in ip-up to set the IPv6 default route but I
have native IPv6 from the ISP so your configuration may need to be
different.
