Disable IPv6 on FreeBSD
Posted Fri, 30 May 2008
I was trying to install something from ports tonight, and package fetching kept hanging for a long time. Turns out, for whatever reason, it was trying to connect to some of the servers on ipv6, which would fail and it would then try ipv4. This is probably due to some change I made recently but forgot about.
At any rate, I needed a quick way to kill ipv6 activity on the machine. Trying '/etc/rc.d/network_ipv6 onestop' didn't seem to have the desired effect, so I added this rule to my pf.conf:
block return out inet6 allEverything is happy now. Probably not the most optimal solution, but I'm not looking for the optimal solution right now.
