Outbound network access blocked on a port 1025

Hi,

I seem to have a problem similar to another poster who posted some time ago. Except, I am trying to connect to port 1025 (Teradata Database connection). I used to be able to connect fine some days ago and it now stopped. I also have a VM Player image running locally on my machine and connecting to that too doesn't work. The applications just hang forever. I must mention that the hosts themselves are reachable, since ssh works. I have turned off firewall, although I used to be able to connect with firewall on.

Any ideas what could be wrong or how I go about investigating this problem?

Thanks
