Remote desktop web connection from behind a firewall - port 80

I would like to access my clients SBS 2003 server via terminal services. Whilst at home I use the normal TS client and this works fine.

However whilst doing my real job (the client is a customer of the business that I run at weekends) I am behind a firewall that I have no control over. I am only able to get port 80 access to the internet.

Is there a way in which I can connect to the mentioned server from behind a firewall. Does RD web client use just port 80 or are there other ports involved?

Any help would be appreicated

Hi Ed,

Ideally port 443 also needs to be open (for Secure HTTP). In addition Port 4125 needs to be open for "Remote Web Workplace". documents all relevant ports.

Hope that helps.

Actually Richard has the right idea... but you don't need 4125 open on the client side, only on the server side.  You do need access to port 443 from where you are trying to connect, but I doubt that they block that if they allow port 80, because you otherwise wouldn't be able to get to any secure sites.

So use Remote Web Workplace, which will do everything through 80 & 443. for an overview. for the webcast demo

Well said - having re-read the question my answer referred to the server side, not the fact his client only had access to port 80.

Thanks for those links - I've learned something new (mapping local drives to remote desktop) myself from them. :-)
