I can't spot anything wrong in what you've shown but it seems you're not looking at all the data you could be looking at. What might help with diagnosing the issue is monitoring the output of: netstat -I gif0 netstat -I enc0 and: netstat -s Look closely at how the counters change, and find the ones which could relate to an OSPF packet being dropped. Also, check if pf is dropping related packets by logging any blocking rules and checking pflog0 with tcpdump as well.
