the server isnt behind any router and you can actually change your own ip by using a proxy

for example when a stupid moderator ip banned this dude, it ip banned everyone, we had to use a proxy to take it off

You cant IP ban anyone at http://lnx.propolingo.com/labb/president/forum/ because apparently everyones ip is the same, how do we fix this, the forum is upto date aswell, the ip is 192.168.117.10
