Supported Session Protocols
The NAT feature supports the following session protocols for both inbound and outbound access with the required
support, applications, and limitations given in the following table.
Certain Internet applications require an Application Level Gateway (ALG) to provide the required transparency for an
application running on a host in a private network to connect to its counterpart running on a host in the public network. An
ALG may interact with NAT to set up state information, use NAT state information, modify application specific payload and
perform the tasks necessary to get the application running across address realms.
No more than one server of a particular type is supported within the private network behind the SU.
These VPN protocols are supported with their corresponding ALGs: IPsec, PPTP, L2TP.
