[Zope-dev] Hard set port number in 2.3?

In Zope 2.2.4 i had the following setup zope box running zope with port 8080 Fire wall with port redirector from local port 80 to zope box port 8080 Everything worked fine, directly accessing the zope box on port 8080 or accessing the firewall on 80. But now with zope 2.3.0 it keeps writing urls going to the firewall box on port 8080 instead of port 80 like it previously did. Anyone know how to fix this problem? Where i should look? Mithro
