When I boot into DragonFlyBSD 1.0A the external network does not work. Here is my configuration and the output of ifconfig and netstat-rn:

ifconfig_sk0="inet 192.168.0.3 netmask 255.255.255.0"
defaultrouter="192.168.0.1"
hostname="toronto"

Funny thing is that my internal network works. I can ping 192.168.0.1 (router) and 192.168.0.2 (second computer). However, external network does not work.

After executing the following two commands, everything works fine:

ifconfig sk0 192.168.0.4
route add default 192.168.0.1

Output of ifconfig and netstat -r is now:

sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

I would appreciate any hints in resolving this "interesting" problem.
