codeigniter website sessions not working...

[eluser]erickoh[/eluser]
I'm able to use the codeigniter.com site, the forum and expressionengine from my office, however these sites dont work properly (in terms of tracking sessions) when I'm accessing from home. For example, searching in the forums or bug tracker never turns up anything from my home, but the same search produces results when I am in office.

My home ISP routes all web requests via a proxy, which usually assigns a different IP address over different requests.

So, is this happening because codeigniter.com and expressionengine.com are specifically setup to use sess_match_ip=true ? Or is this due to some bug in CI, such as
http://codeigniter.com/bug_tracker/bug/4336/

Hope I can get some answers as I am evaluating expressionengine as a CMS but the "faulty" session tracking is holding me back

Thanks!
