ipv4 & ipv6 Virtual Hosting - address in use

[David J.]

Thanks for the responses;

I am running ubuntu 10.10 on these particular instances;

I was able to get it working however; its going to the first server 
configured;

So I am still not quite sure how to fix;

I will try playing around a bit more.

Thanks.
