jails and one dynamic ip address

2010-05-25 Thread Fbsd1
I get one dynamic ip address from my ISP. This is what I specify on the 
jail for public network access. When the ip address changes on me I have 
to manually change the ip address associated with the jail.


Is there some method I can code so jail will all ways have public 
network access?

Hi,


Sure there can be a better solution (I think :)):

Use an rfc1918 private address range for your Jail, and use nat, to forward
your external interface IP to the private address of the jail.

This can be done in ipnat, PF, or the other natting, packet filtering tools.

Hope I understood your question :).

Regards,

Balázs M.

The jails are on the host with LAN behind it and with ipf firewall which 
allows out anything coming from LAN private ip address. I was not able 
to get this to work until I discovered the jail needed a copy of the 
hosts /etc/resolv.conf. Now it works without any special tweaks, and the 
dymanic ip address changing causes no problems.
