UDPTimeout UDP Timeout for NAT in seconds
(note: 0 {zero} disables UDPTimeout)
The default value for removing a non−TCP NAT Session due to inactivity is 300 seconds
(five minutes). It has a range from 0 to 3600 seconds (one hour). A value of zero will cause
non−TCP NAT Sessions to never be removed due to inactivity. Use this option with caution
because it is possible for the router memory to eventually be occupied by the NAT translation
session database.
TCPTimeout TCP Timeout for NAT in seconds
(note: 0 {zero} disables TCPTimeout)
The default value for removing TCP sessions due to inactivity is 86400 seconds (24 hours). It
has a range from 0 to 172800 seconds (48 hours). As for the UDPTimeout, a value of zero
will cause TCP NAT Sessions to never be removed due to inactivity. Also use this option
with caution because it is possible for the router memory to eventually be occupied by the
NAT translation session database.
TCPSynTimeout TCP SYN Timeout for NAT in seconds
TCPFinTimeout TCP FIN Timeout for NAT in seconds
The default value for these variables is 180 seconds (three minutes). They have a range of 20
to 300 seconds. They cannot be disabled.
InternalRange Strings for Internal IP addresses,
(parsed like filters)
This is one of the two most important variables in the [NAT Global] section. This is the range
of IP addresses that will be translated into the range of IP addresses set by the ExternalRange
