Mod_proxy breaks wiki server

Question

I have been using wiki server to manage collborative content amongst a small number of physically disparate users.
I recently enabled forward proxy on the httpd server, which is also a NAT gateway and firewall.
When I 'control access' to the forward proxy (only allowing local IP's), wiki server can't serve content to external IP's any more.
[Sat Jun 06 08:01:46 2009] [error] [client 124.170.77.5] client denied by server configuration: proxy:http://127.0.0.1:8087/groups/lineup/
If I use a VPN I can access wiki content (because my source IP is local rather than external), but unfortunately VPN is boring as the auto-connect feature in leopard is broken. I also want to be able to serve wiki content to people without giving them VPN access.
local IP address range is 192.168.1.0/24
forward proxy access control is 192.168.1
I have asked mod_proxy not to cache localhost....to no avail.
thanks in advance!

Answer 1

Ok. Fixed the mod_proxy / wikiserver thing. Just had to let the proxy know that requests from the internal webserver were ok;
I mean that seems obvious, but if the internal webserver has an external IP, it doesn't automatically do it....so you have to put a No Proxy command in httpd.conf covering all your external IP's, localhost, 127.0.0.1 etc until finally the webserver doesn't proxy itself and deny itself access to itself.
of course you can't edit No Proxy settings from within Server Admin.
so that's done and wiki now works for the planet rather than just local IP's.
