As with any NAT solution, applications that carry IP addresses in the payload (i.e., give the IP address for a computer as part of the data inside the packet) will not work. This is true industry-wide, so care must be taken to understand the applications that you are using to ensure that NAT will solve your problem. In particular, H.323 (Netmeeting) will not work with NAT.

HOWEVER, a fixup module is included that allows active FTP over NATed connections. Active FTP is usually forbidden on NATed subnets.

NAT will not function correctly for Corente Clients because these clients are bridged directly to the Location gateway’s LAN.
