[mssclamping]
166
A number between 1 and 1024.
Represents the maximum number of IP packet fragments waiting for
completion.
Generally the fragmentation limit is 64.
By limiting the fragmentation limit the depletion of the buffer is
avoided.
Define which packets are reassembled under which circumstances.
Choose between:
normal
•
Packets to be forwarded will not be reassembled.
Packets with local destination, i.e. destined for the Speed-
TM
Touch , are reassembled.
always
•
Packets are always reassembled.
nat
•
Same behaviour as normal except for packets to be forwarded
through the Network Address Translation (NAT) engine.
Packets on which address translation is performed are reas-
sembled as the NAT engine requires the entire packet.
Set the level of IP address checks.
Choose between:
off
•
No address checking is performed.
For advanced users only; in normal circumstances there
should always be some kind of address checking.
own
•
Minimum level of checking.
Only the address configuration on the SpeedTouch
checked.
static
•
Checking of the address configuration of the SpeedTouch
and also of traffic: addresses of incoming packets; this checking
is related to constants (e. g. an address may not be entirely
composed of one's or zero's).
dynamic
•
Besides the address configuration of the SpeedTouch
and besides the checking of traffic on a constants level, addi-
tional checking is performed on the IP addresses that are
determined by the configuration, more specifically by the
network.
Disable (off) or enable (on) mss clamping for low mtu interfaces.
Mss clamping assures that the size of a TCP packet never exceeds
the available mtu of the outgoing interface.
It is recommended not to disable this parameter.
