Subject Re: Help with external DHCP issue
Date Sun, 14 Feb 2010 07:18:26 GMT
Thanks James.  I added the VMs to my /etc/hosts file and my dhcpd.conf file,
and the same thing is happening.  I think the dhcp was working fine before,
but VCL seems to be getting confused between what the public IP address is
and what the private one is.  Here is a snippet from the logs:

As you can see, its taking the public IP (134.154.119.175) and making it the
private one, and vice versa.  End result is that it asks me to RDP to the
private address, which of course is impossible.

If I RDP to the 134.154.119.175, I can login just fine.  I just need VCL to
present that IP address to me instead of the private one.

Any ideas on this?

Thanks,
Jeff
