Wiki

We've been experimenting with switching our firewall, filtering and other network features to open source and were recommended Untangle as a solution many schools were already using. The interface is really great and it's something we'd like to adopt, however we have encountered a problem with our Moodle when just running the firewall element.

The problem is very like the one reported last November (http://moodle.org/mod/forum/discuss.php?d=85423) in that when a wiki page is updated, clicking on the save button, the progress bar goes about half way then stops and just hangs there for several minutes and never completes the refresh to the 'Thank you' page. Closing the window and trying to simply return to the Moodle also fails ie: it just says "waiting". If you return in 10 to 15 minutes, then you can get in again and the wiki page has been updated correctly. If we switch back to our old firewall then the wiki module works fine.

The other posting suggest there is a bug in the wiki module but does not really explain what the problem is. At first we though it was a port problem, but opening all ports does not solve it. Any intelligence or thoughts would be appreciated.

We're running 1.8.3+ on an external hosted service (Demon in the UK) with mysql 5.0.20 and php 5.1.4.
