Thread:Project:Support desk/$wgServer question - Access OK locally but not remotely

This is likely linked to the "Wiki appears without styles applied ..." problem in the Errors and Symptoms page here ... but is different enough to be troubling.

Set-up: MediaWiki 1.20.2, PHP 5.3.10, MySQL 5.5.29, Apache 2.2.22 so pretty up to date. Development URL (if you'd be so kind as to take a look): http://prestwood.no-ip.org/mediawiki/

Setting $wgServer to the internal server address and accessing the URL via the intranet (10.231.0.100) works fine in Firefox and URL.

Setting $wgServer to various external server address and accessing the URL via the external address (e.g. prestwood.no-ip.org) leads to extremely long load times on a blank screen. If I chip in and hit ESC, the rendered web-page had well formed links and I'm OK on the "Max made me put this here" test (also no problems with PHP logs that I can see). It seems to be a Javascript symptom as, if I load the No-Script JS disabler on Firefox, the page loads quickly and all is OK.

My server seems to be performing DNS lookups on the external address OK:

And I think my apache conf file is broadly OK:

Nothing in the apache error.log. The access.log says this:

(10.231.0.1 is the external facing router, of course)

Realise that I probably haven't given enough to help someone help me yet - has anyone any ideas where I should next investigate this?

Cheers
