Controlling Multiple Macs - any other options?

From home I have used teleport to do this successfully. However, at work, I can't get either Mac to recognize the other. It's really a pain. Any suggestions?

I have tried reinstalling teleport, but it didn't seem to work. I'm thinking it may be some type of wireless security the company has in place.

Any other program suggestions would be appreciated.

 

I installed this and I have the same problem. Both programs are active, but the computers can't see each other. They are both online via wireless network, and sitting literally right next to each other....
