Problem Connecting through Linksys router

Hello,

I have a linksys 4 port cable router myself at home and am able to connect to my office computer and vice versa without a problem.  Attached is a screenshot of my port forwarding setting page for my router.

Matthew has got this right.  The trick to getting it to work in either direction is to remember to enter in the REAL IP address (32.4.3.7) of the machine that you are trying to connect to, not the 192.168.1.1 address on the other side of the router.

Check with your office sys admin on being able to communicate through ports 5800 - 6000.

And you don't by chance also have firewall software running at home too?

Later,
KMF
