My requirement is to run multiple DomU's on public IP Addresses for things like mail servers and stuff, but I also have a further requirement to run multiple DomU's on private IP addresses for other services. With your help, I've been able to get a couple of DomU's working on public IP's and there was no problem in that regard, however, the DomU's on the private IP addresses simply won't connect beyond the Dom0. I can ping the Dom0 and ssh to it from the DomU, but can't ping google.com (or anything else) or ssh to an external server. I can do these things from the Dom0 and from the DomU's with public IP addresses. I've googled, but have not found and answer and was wondering if there was something you could suggest. Cheers Erich Hi there,

Thanks for this great article.

Make sure the IP address of the Dom0 in that file is correct (78.46.35.5 in my case) and that you've added the route commands correctly then run: ifdown eth0 ifup eth0 and see if that helps perhaps?
