Hi Tom, i don´t think so since the internal vpn configs do their config field separation via comma. In this case only the 13th field will be read out.

Fix for bug #11614 Set other variable name for better understanding. Set another variable for remote subnet searcher to make the IPTables command better understandable. Deleted COUNTER lines since they are never used. Deleted variable to VPN configuration files since both are used only once. All changes has also been applied to IPSec section.
