Adventures in Tech: Taking the plunge into IPv6

There are a number of issues with IPv6 based on experience.

The biggest issue, and one that touches on the issue of NAT, is how to cope with multiple ISP circuits. We have the position where, being out in the sticks, high capacity bandwidth is expensive so we direct HTTP traffic over an ADSL line and anything else over a leased line circuit.

The problem is that without NAT on the IPv6 traffic and a unique global address on each internal host the only way I can find of making sure that the return path is to the same interface as the outbound route is to NAT the interface otherwise the return path is always back to the primary path for your unique host address.

Alternatively you can think about source routing and really give yourself a security headache.
