Hi all
I am experiencing the same issues.
I have some additional info.
I am running in GW mode with 2 nic's.
1 nic is local lan
1 nic is my inet ip
When I browse from my internal lan, resolutions are fine
eg ...
www.primary-ibay.bla = primary-ibay
.........
www.secondary-ibay.bla = secondary-ibay
BUT when I do it from the inet to my (single) ip with multiple domains configured, I keep getting the primary-ibay contents.
I've doen extensive test with right/various ibays to no avail.

Could someone show us some LIGHT ?
This is before I start hacking the apache conf's .....
Which I rather not do as I am really starting to appreciate the elegance of the templates

(B) to all.
Neil.
