I started telnet inside the jail, to the world:
[root@splash /usr/home/goya]# jail -l -U root -i /usr/jail/ro.noc
r-noc.net.bme.hu "2001:738:2001:1000::2" /bin/sh

# ifconfig lo0 ; ifconfig lo1
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
lo1: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
inet6 2001:738:2001:1000::2 prefixlen 128
# telnet 2001:738::abcd
