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)
|
+-- epair1a --+-- epair1b 192.168.1.2(ns1)
|
+-- 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:
