Thanks for the links, it's a whole new world out there once the extra security of the NAT function and the port forwarding is stripped off so I want to get it right. I haven't gotten my head around load balancing from two ISPs (presumably with two different IPv6 address allocations) yet, so it's just as well one of mine doesn't do IPv6. As an aside, "routeing" is correct in English, "routing" is the US variant. In the UK, "routing" is the act of machining a slot in a piece of wood or similar (amongst several other meanings, some of which I didn't know until I just looked it up).
