Simple Firewall |
 |
A simple firewall can not handle H.323. A application based firewall
should be able to do this but this is quite hard to implement.

VirtualPrivateNetwork (VPN) |
 |
The terminal PC becomes a member of the LAN. This solves the security
issues but needs more bandwith.
For ADSL and xDSL Telekom Austria uses VPN technologies. |
