FreeBSD - 감옥 내부에서는 인터넷에 연결되어 있지 않습니다.

저는 현재 FreeBSD에 서버를 설정하려고 합니다. ezjails를 기반으로 감옥을 만들고 싶습니다수동. 예제를 따라 Jail 내부에 BIND를 설치했는데 설치 단계( make -C /usr/ports/dns/bind99 install clean)에서 막혔습니다.

처음에는 DNS 문제가 있는 줄 알았는데(나쁨 /etc/resolv.conf) 교도소 내부에는 인터넷이 전혀 안되는 것 같습니다.

호스트: (8.8.178.110은 www.freebsd.org입니다)

root@varda:~ # nc -z -w 2 8.8.178.110 80
Connection to 8.8.178.110 80 port [tcp/http] succeeded!

감옥 내부:

root@dns:~ # nc -z -w 2 8.8.178.110 80; echo $?
1

무슨 일이 일어났는지 아세요?
