Can't access from work, port blocking

Most of the ports at work are blocked.

I can access vibe from home, my iphone, but I can not access it from work. I've tried port 440, 808, 8081.

8080 works, but I use that for my server.

I can't figure out exactly which ports are block by the company firewall. Any suggestion as to a common port that won't be blocked or some program that I can run that will test them?

Thanks

You might wanna configure an apache http server that serves port 8080 and forwards you to whatever internal port you're running whatever service on, based on the requested domain. There are some posts on it here on the forum, just search for "apache".

Otherwise I'd recommend you to try out port 443, which is the default SSL port. You might even wanna configure SSL while you're at it... (since you can never be too secure )
