I got a bleeding edge ver of NetBSD (9.5?) running on a spare drive. I figured out how to connect to the internet and get name service.
If I go into rc.conf and set the following: ipmon=YES ipfilter=YES and reboot -- then I CANT PING ANYONE. If I turn off ipfilter using /etc/rc.d/ipfilter onestop. I can now ping google.com with no problems. What is going on? Is something set incorrectly?
