Hello everyone,
I'm having a strange networking issue in my jails (not in the host)
Sounds like whatever DNS server I use in my jail's resolv.conf I get
something like this:

First time: works
20:41:44.456468 IP 191.121.159.155.53848 > 4.2.2.1.53: 33178+ ANY?
www.google.com. (32)
20:41:44.470159 IP 4.2.2.1.53 > 191.121.159.155.53848: 33178 1/0/0
CNAME www.l.google.com. (52)

Second time: Timeout
