problems with make world process

[andy at neu.net]

I am trying to use the make world process and am having a major problem.
Everything goes well until the last step.

First I tied upgrading to 4.9 stable by:
cvsuping RELENG_4
make buildworld
make buildkernel
make installkernel
reboot (single user)
mergemaster -p
make installworld
mergemaster
reboot

When I reboot the network is totally broken, if I try to ping 192.168.1.1
my local gateway I get:
ping: sendto: No route to host

So, I thought maybe the mergemaster process hosed things up.  I did the
whole process again and instead of running mergemaster, I rebooted after a
successful installworld.  Again, same thing the network is broken.

Then, I thought maybe something is wrong with 4.9, so I repeated the
exercise again twice going from 5.2.1.Release to 5.2.1.p4.  And still no
luck.  So, I am obviously missing something big or small (or both).

The purpose for doing this is to build a firewall by following the
directions
at:http://www.schlacter.net/public/FreeBSD-STABLE_and_IPFILTER.html

Everything looks ok as far as ifconfig and /etc/rc.conf are concerned.
What can I  do to troubleshoot the network problem?  Any advice would be
greatly appreciated.  TIA
