[Help] Character restriction

Hello folks then .. :-[

I need help with my AIOs since restrict them from leaving towns is hard

so I would know how to use a punishment for such

In L2TownZone.java this

protected void onExit(L2Character character)
{
	// TODO: there should be no exit if there was possibly no enter
	if (_isPeaceZone)
		character.setInsideZone(L2Character.ZONE_PEACE, false);

	character.setInsideZone(L2Character.ZONE_TOWN, false);

if (character instanceof L2PcInstance)

{	
		if (((L2PcInstance)character).isDonator() && getTownId() == 7)

		{
			((L2PcInstance)character).sendMessage("AIOs can't leave town. You are now back.");
            ((L2PcInstance)character).teleToLocation(MapRegionTable.TeleportWhereType.Town);
		}
		else if (((L2PcInstance)character).isDonator() && getTownId() == 8)
		{
			((L2PcInstance)character).sendMessage("AIOs can't leave town. You are now back.");
            ((L2PcInstance)character).teleToLocation(MapRegionTable.TeleportWhereType.Town);
		}
		else
			((L2PcInstance)character).sendMessage("You have entered a non-restricted area.");
			 		}

  }		

It works, but the restriction also applies when it goes to Town to Town .. here's how to limit access only to towns with ID 1-13!?

thx
