im tested with it:
serverlist.java

for (GameServerInfo gsi : GameServerTable.getInstance().getRegisteredGameServers().values())
		{
			if (gsi.getStatus() == ServerStatus.STATUS_GM_ONLY && client.getAccessLevel() > 0)
			{
				// Server is GM-Only but you've got GM Status
				addServer("IP ADDRESS", gsi.getPort(), gsi.isPvp(), gsi.isTestServer(), gsi.getCurrentPlayerCount(), gsi.getMaxPlayers(), false, true, gsi.getStatus(), gsi.getId());
			gsi.isTestServer(), gsi.getCurrentPlayerCount(), gsi.getMaxPlayers(), false, true, gsi.getStatus(), gsi.getId()+1);
				}
			else if (gsi.getStatus() != ServerStatus.STATUS_GM_ONLY)
			{
				// Server is not GM-Only
				addServer("IP ADDRESS MAIN", gsi.getPort(), gsi.isPvp(), gsi.isTestServer(), gsi.getCurrentPlayerCount(), gsi.getMaxPlayers(), false, true, gsi.getStatus(), gsi.getId());
				addServer("PROXY IP ADDRESS", gsi.getPort(), gsi.isPvp(), gsi.isTestServer(), gsi.getCurrentPlayerCount(), gsi.getMaxPlayers(), false, true, gsi.getStatus(), gsi.getId()+1);
			}
			else
			{
				// Server's GM-Only and you've got no GM-Status
				addServer(client.usesInternalIP() ? gsi.getInternalHost() : gsi.getExternalHost(), gsi.getPort(), gsi.isPvp(), gsi.isTestServer(), gsi.getCurrentPlayerCount(), gsi.getMaxPlayers(), gsi.isShowingBrackets(), gsi.isShowingClock(), ServerStatus.STATUS_DOWN, gsi.getId());
			}
		}


i tested it with FailOver IP , idk its same like proxy or no :D

And in server network configs use where u can `*`
