Below is more detail: If we say network A = 62.220.237.x and B = 62.236.221.x My guest systems are: - name server (port 53) (network B) - mail server (80,443,25,465,995.993,563,636) (network A) - secondary mail server to a mail server in another box (25,465) (preferably network A AND B, for maximum availability) - a test system, can be in either network (but port 22 required) Of course I could rearrange, for example set up another xen box for one of these mail servers. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi * http://www.greenspot.fi
