With some dns requests, pf denies the connection, but with others not. For example, if I do a query about www.oracle.com or www.microsfot.com for example, all works ok. But if I do a query about www.freebsd.org or www.openbsd.org, request is denied: 00:00:02.610710 rule 29..16777216/0(match): block in on vtnet1: (tos 0x0, ttl 52, id 23787, offset 0, flags [+], proto UDP (17), length 1492) 8.8.8.8.53 > 172.30.77.2.50068: 5832$ 7/0/1 org.

I am using an internal unbound dns cache server installed on a Debian host and I have configured Google's DNS servers, 8.8.8.8 and 8.8.4.4, as a forwarders. I have tried to disable these forwarders in unbound's config, but same error occurs. Any idea why?? Thanks. -- Greetings, C. L. Martinez
