To get rid of a realm loop.Edit your realms config to look like this

<Realm1 Name = "Some realm"
Address = "127.0.0.1:8129"
Icon = "PVP"
Colour = "1"
Population = "1.0"
TimeZone = "1">


<Realm1 Name = "WoWica"
Address = "your dydns:8129"
Icon = "Normal"
Colour = "1"
Population = "1.0"
TimeZone = "1">



Then scroll up and edit this

<LogonServer Address = "127.0.0.1"
Port = "8093"
Name = "logon"
RealmCount = "2">


then close and save then boot your realm up. And it should Work =P
