You can use netmeeting and remote desktop and open the ports through the firewall

how secure is netmeeting ??  depends on your firewall and your system configuration

As it turns out, netmeeting is very problematic to use with NAT. The reason is that netmeeting embeds the destination IP address in the datagram in addition to the header. The only way to get these packets past NAT is with a NAT implimentation that specificly supports netmeeting. Some Linux based firewall do this with additional modules. No hardware based firewall that I am aware of can do this.

The best solution would be to use VNC or VPN. These work at layer two of the protocol stack and are not effected by the above problem.

any idea  if vnc is secure or not?
Jay DubyaUC EngineerCommented:
UltraVNC offers NT security which as pretty good, also offers a less secure option where you can set the password and everyone can log in provided they have that password.
Glad I could help!
You could always use RealVNC or cant remember. It can be setup to use SSL for security and you only need a small amount of ports open to use it. You cna also have multiple clients conected to one machine and is highly modifiable depending on the spee dof your connection i.e. if your connection is slow you can turn the screen size and colours down etc.
