Re: Jails within different networks ... ?
I've actually done that but the result was jails coming up incredibly slowly and once up basically not wired. I'm gonna check my configuration again and I'll update the mailing list soon. Thanks for you time to you all.

Re: Jails within different networks ... ?
Just an update. It seems to be working well. The jail startup slowness I believe is due to the fact that the DNS is still down.

Jails within different networks ... ?
Hi there, I've a doubt! I have 3 jails within the host xxx.xxx.26.224 configured in this way (below) and everything works well. What if I want to enable another jail but I don't want to assign to that my next available public ip address xxx.xxx.26.228/24 but I want this jail to have a private ip address like 172.16.1.2/27? Is that possible or it's a delirium? I don't want to waste my public ip address for a jail which I want to have a network configured but not to be publicly visible. Many thanks in advance. lagg0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8009bRXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE ether 00:14:5e:ee:2b:c0 inet xxx.xxx.26.224 netmask 0xff00 broadcast xxx.xxx.26.255 inet xxx.xxx.26.225 netmask 0x broadcast xxx.xxx.26.225 inet xxx.xxx.26.226 netmask 0x broadcast xxx.xxx.26.226 inet xxx.xxx.26.227 netmask 0x broadcast xxx.xxx.26.227 media: Ethernet autoselect status: active laggproto failover laggport: bge1 flags=0 laggport: bge0 flags=5MASTER,ACTIVE -- Caselle da 1GB, trasmetti allegati fino a 3GB e in piu' IMAP, POP3 e SMTP autenticato?
