ping for a period of time, let the session expire, then restart the ping. The expiration time
differs from protocol to protocol.
7. With dynamic WAN interfaces, the Route table changes as links go up and down. Since
NAPT is based on Route Table, NAT packet forwarding may behave differently from
time to time.
Static Session Mapping: Static session mapping is used in both NAT mode and NAPT mode.
1. The static session mapping used in NAT mode and NAPT mode are the same except for
one difference. Only one session mapping is effective per WAN Network Interface in the
NAT mode, while there is no limit in the NAPT mode.
2. Session mapping maps a local host IP address to a WAN Network Interface. You must
first create a Session Name and associate it with the intended WAN Network Interface.
Then you can map local host IP addresses to that Session Name.
3. Depending on the memory resource availability:
i. Up to 64 Session Names can be created for each WAN Network
Interface.
ii. Up to 64 Session Names can be created in the system.
iii. Up to 253 Local host IP mappings can be created for each Session Name.
iv. Up to 253 Local host IP mappings can be crated in the system.
