I realize this thread is six months old, but I'm not finding much along these lines...
I'm actually having the same 'problem'. I have two internet-registered domains. The first I use internally, and the second externally. The first domain, we'll call 'fs', is pointed at the 'fs' ibay and works fine. The second domain, 'wod', is pointed at the 'wod' ibay.
Web mail and ACID work fine (those aren't in ibays). What's not working are the ibays I set up for netjuke and MRTG. Netjuke and MRTG work fine when I go to
www.fs.com/netjuke or
www.fs.com/mrtg from the LAN or from the 'net.
www.wod.com/netjuke and
www.wod.com/mrtg don't work at all.
Is there something I can modify so the mrtg and netjuke ibays are accessible from my virtual domain as well as my primary domain?
[fs.com and wod.com are not my domains, just examples. those names are actually what I called my ibays. the domains will resolve on the net and I am not affiliated with them in any way.]
