firewall problem (maybe)

Hello,

I'm trying to access a subversion repos on a server external from my office. From home I have no problem accessing it, but from the office no luck. First I tried accessing an authentication required repos, but was only getting the "svn : PROPFIND request failed on http://site/svn/etc", so I tired accessing a publicly available repos with the same results.

I'm not using SSH, so my assumption is that the connection would be happening on PORT 80, which is not blocked at my org. Also, I can access both repos from my browser.

I'm using SVN 1.3.0.

I'm guessing it is likely a firewall issue, but I'd like to confirm it. Has anyone experienced a similar issue and if so, did you resolve it and how?

Thanks
