I don't know if somethng has been changed over time, but if you run some service in host on IP assigned to jail on port not used in jail, there will be no conflict and service will be available to public e.g: ntpd on host listening on all available IP addresses # sockstat -4l | grep 123 root ntpd 1186 20 udp4 *:123 *:* root ntpd 1186 22 udp4 192.168.22.56:123 *:* root ntpd 1186 23 udp4 192.168.23.43:123 *:* root ntpd 1186 24 udp4 xxx.yyy.zz.27:123 *:* root ntpd 1186 25 udp4 xxx.yyy.zz.28:123 *:* root ntpd 1186 26 udp4 xxx.yyy.zz.29:123 *:* root ntpd 1186 27 udp4 xxx.yyy.zz.30:123 *:* root ntpd 1186 28 udp4 xxx.yyy.zz.31:123 *:* root ntpd 1186 29 udp4 xxx.yyy.zz.32:123 *:* root ntpd 1186 30 udp4 xxx.yyy.zz.33:123 *:* root ntpd 1186 31 udp4 xxx.yyy.zz.34:123 *:* root ntpd 1186 32 udp4 xxx.yyy.zz.35:123 *:* root ntpd 1186 33 udp4 xxx.yyy.zz.119:123 *:* root ntpd 1186 36 udp4 127.0.0.1:123 *:* root ntpd 1186 38 udp4 10.13.26.1:123 *:* root ntpd 1186 39 udp4 10.13.25.1:123 There are 7 jails, each with one or more IP addresses. No problem. Miroslav Lachman
