Dear stable list,

I've created private network by Vimage Jail using ezjail referenced [1] as
follows:

em0 X.X.X.X bridge0 192.168.1.254 --+-- epair0a --+-- epair0b 192.168.1.1(ns)

                                    |
                                    +-- epair2a --+-- epair2b 192.168.1.3(cvs)
                                    |
                                    +-- epair3a --+-- epair3b 192.168.1.4(mail)

                                    +-- epair4a --+-- epair4b 192.168.1.5(web)

where X.X.X.X is the global address of outer network. All jail environments
are under /jails:

(1) Vimage Jail startup scripts' patch according to [1] is [3]
(2) /var/log/messages is [4]
(3) ezjail startup files are [5]
(4) /etc/devfs.rules is [6]
(5) /etc/rc.conf is [7]
(6) Jail envirinments' fstabs' are [8]
(7) pf(4) configuration file is [9]

Is there any suggestions? 

Best regards
