I have to admit that I have been running out of ideas why the wiki cannot get a connection while "curl" can.
One last try: has the gateway connecting the local network to the internet an application firewall or the like ? Something that sniffs user-agents for http connections and only allows "known ones" ? The java client used by the XWiki installation wizard might be emulated with: curl --user-agent "history" http://extensions.xwiki.org if this works, too, I have to admit I have no clue why it does not work. (Btw, there should be an error message in the log files. Is there anything like that?)
