The major difficulties in using remote control software are firewalls and blocked ports, as well as NAT routing for local IP addresses. If you use TeamViewer you don't have to worry about firewalls: TeamViewer will find a route to your partner."
If your work system is pulling DHCP from the workplaces internal network, ie class A subnet 10.10.10.10, there is no way you will directly get to it from the internet. There will have to be some sort of port forwarding at the gateway to get to it, either by MAC or IP forward, and that is configured at the gateway.
That being said, I should place a caveat on it. If the gateway is properly configured with security in mind. At my place of employment, there is no direct way to my workstation from the outside. FWIW, as an experiment, we have tried teamviewer and couldn't get it to work. Didn't involve their support however.
edit: just confirmed that upnp traffic is blocked at the gateway at my work which would cause some problems. Ultimately, if there is a hardware firewall involved, there would need to be some open configuration to allow any remote access to work.Edited by straha - 1/24/11 at 2:06pm
