Sure, here it is. xl1 is the LAN interface, tun0->xl0 is the PPPoE interface:
[EMAIL PROTECTED]:/etc] 7 $ ifconfig -a
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
ether 00:60:97:a7:c9:01

Notice there are no IPv6 configurations. I put
net.inet6.ip6.auto_linklocal=0 in /etc/sysctl.conf as part of a
troubleshooting test to get PPPoE to work(*). I left it in after I
got PPPoE working because I don't use IPv6, but removing "options
INET6" from the kernel makes pf, ipfilter, and ipfw klds complain
loudly.
Cheers,

(*) Long story. It took over 8 hours to get the PPPoE connection
working after the install. tcpdump would segfault during the PPP
handshaking do I couldn't even figure out what was going on. I
finally got it to work by putting "disable ipv6cp" in my ppp.conf
file. Otherwise it would sit and wait for carrier forever after the
first attempt.
