I'm with you mate. However, disabling something that you don't understand and is enabled by default on a system for which it probably wont work fully anyway isn't too bad an approach. That said, I will be using IPv6 to route around the sheer naffness of 192.168.0|1 at customer sites. Quite a few businesses have a networking legacy, shall we say. I currently use OpenVPN and a 1:1 NAT (see https://doc.pfsense.org/index.php/OpenVPN_NAT_subnets_with_same_IP_range https://doc.pfsense.org/index.php/OpenVPN_NAT_subnets_with_s...) With IPv6 and a little DNS work I can make routing work again - smashing!
