I don't want the IP to be redirected, I would like the jail to have It's own IP. Redirection would probably involve a NAT on your main IP to the IP of the jail, which is something I would like to avoid. Did you use something like the aforementioned ifconfig alias to give the IP to your jail ? ifconfig_bce0_alias0="inet 1.2.3.4/32" What bothers me is that I am not able to ping from the outside either ?? And I can't install any ports because I don't have any network available inside the jail. ---------> Grιgory Bernard Director <--------- ---------------> www.osnet.eu <--------------- --> Your provider of OpenSource appliances <-- OSnetOSnetOSnetOSnetOSnetOSnetOSnetOSnetOSnetO
