[pups] Networking With 2.11 BSD and Begemot Emulator

I've been trying to set up an emulated PDP-11 running 2.11 BSD. Just for
the fun, I'm trying to get the 11 to talk on a LAN. Unfortunately, it's
not working.
My configuration is Begemot P11 Version 2.7 running under
FreeBSD 4.1.1. I've booted 2.11, configured a custom networking kernel,
installed the unix and netnix images, changed the IP addresses in
/etc/hosts to match my LAN, run mkhosts to rebuild /etc/hosts.dir and
/etc/hosts.pag and rebooted.
On the P11 front, I've built a fake qma.rom file populated with zeros --
just like the P11 README file said, made sure that I had a tun driver
configured in my FreeBSD system, and started P11. Then I did an
ifconfig tun0 host-IP-address emulator-IP-address up
Running ifconfig on the host confirmed that things *seemed* to be OK:
# ifconfig tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1518
inet6 fe80::260:8ff:febd:5882%tun0 --> :: prefixlen 64 scopeid 0xb
inet host-IP-address --> emulator-IP-address netmask 0xffff0000
Opened by PID 32199
The IP addresses are identical in the first three octets, and differ only
in the last octet.
Unfortunately, once I boot 2.11 BSD, I can't contact the "outside
world" from the emulator, nor contact the emulator from the
outside. No telnet, no ftp, pings just hang.
Everything looks OK from inside:
# ifconfig qe0
qe0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING>
inet emulator-IP-address netmask ffff0000 broadcast Bcast-IP
What am I missing?
Thanks in advance,
Frank
