ATM Class:

The Quality of Service for ATM layer.

NAT:

through a single IP account, sharing the single IP address. If users on your LAN have public IP
addresses and can access the Internet directly, the NAT function can be disabled.

MTU:

that IP will attempt to send through the interface.

TCP MSS Clamp:

It is enabled by default. All TCP traffic routed through the interface will be examined.

If a TCP SYN (synchronize/start) segment is sent with a maximum segment size larger than the interface
MTU (Maximum Transmission Unit), the MSS option will be rewritten in order to allow TCP traffic to pass
through the interface without requiring fragmentation.
