I installed a small mediawiki on a Linux/Apache server for internal use on
our university laboratory group. The wiki is fully readable both within and
out of the university network. However when I try to edit it *outside* the
university network, on saving the page it waits and then times out, like it
couldn't properly connect. Using a VPN solves the problem, however I'd like
to know if I can fix this issue since sometimes this would require me to
switch between VPNs during work, which is annoying.
What can I do to troubleshoot this issue?
