The MSS should be 40 bytes less than the largest packet the implementation 
can re-assemble.

Interface filter shows whether or not the Nortel VPN Router Firewall is in 
use (this reflects the selection on the Services
 > Firewall window). 
This entry also shows the interface filter that is currently being used by the 
Nortel VPN Router Firewall. Select from a list of all interface filters that have 
been set up on the Nortel VPN Router (on the Profiles
 > Filters window), and 
to select a different filter for the Nortel VPN Router Firewall.

Use the New Interface Filter link to go to the Profiles
 > Filters window and 
create a new filter. The default Interface Filter setting is Deny All.
You can copy an existing tunnel filter for use as an interface filter or vice versa. 
However, when you copy a filter, the operation does not copy any components 
(such as a rule, port, protocol, or address) that have the same name as an existing 
component in the destination filter set. You should use unique names for the 
device in all filter rules.
Note: 
If you change the interface filter setting, a message informs you 
that you must restart your Nortel VPN Router before the new interface 
filter is used. If the Nortel VPN Router Firewall is not enabled, the new 
selection has no effect.
