Config sample (we mean that in /usr/jails/jail1 we have a complete freebsd base environment): % cat jail1.conf jail1 { exec.start = "/bin/sh /etc/rc"; exec.stop = "/bin/sh /etc/rc.shutdown"; exec.clean; #mount.devfs; host.hostname = "jail1.my.domain"; path = "/usr/jails/jail1"; allow.raw_sockets; allow.socket_af; allow.chflags; allow.sysvipc; ip4.addr = 10.0.0.1,10.0.0.2,172.17.0.0/16,10.0.0.3; interface="em0"; mount.devfs; devfs_ruleset="4"; } // Before jail creation, interfaces em0 have: % ifconfig em0 | grep "inet " inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255 // Jail start: % jail -f jail1.conf -c jail1 jail1: created .. //done. Check for IPs on interface. 172.17.0.0 have correct mask: ifconfig em0 | grep "inet " inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255 inet 10.0.0.1 netmask 0xffffffff broadcast 10.0.0.1 inet 10.0.0.2 netmask 0xffffffff broadcast 10.0.0.2 inet 172.17.0.0 netmask 0xffff0000 broadcast 172.17.255.255 inet 10.0.0.3 netmask 0xffffffff broadcast 10.0.0.3 //Check for IP in jls: % jls -v JID Hostname Path Name State CPUSetID IP Address(es) 1 jail1.my.domain /usr/jails/jail1 jail1 ACTIVE 2 10.0.0.1 10.0.0.2 172.17.0.0 We have 10.0.0.1/32,10.0.0.2/32 and 172.17.0.0/16 but loose 10.0.0.3 >Fix: >Release-Note: >Audit-Trail: >Unformatted:
