Tomorrow I buy a server, can send up to study together, I know the way is to set up iptables -t nat -A POSTROUTING -s 10.1.0.0/24 -j SNAT --to-source "1.1.1.1" iptables -t nat -A POSTROUTING -s 10.2.0.0/24 -j SNAT --to-source "2.2.2.2"
I understand to buy more than 2 IP VPS, try, but others seem to be able to set a lot of IP, if you modify the database, it seems that users can not quickly change his intranet IP in the database. Frequent revision?
