|Impose MTU limit (force fragmentation)||MTU (Maximum Transmission Unit) represents the maximum size of an IP packet.
If this option is selected, the next field will be enabled and you can define your limit.
|Maximum MTU value||Define the maximum value of the IP datagram, between 140 and 65535 bytes.|
|Minimum fragment size (bytes)||The fragment must be between 140 and 65535 bytes.|
|Session will expire in (seconds)||This period must be between 2 and 30 seconds.|
|Enable stealth mode||In stealth mode, the firewall does not respond to detection attempts - ICMP requests in particular - so that it appears invisible.
Stealth mode is disabled by default and can be enabled by selecting this checkbox.
The IP protocol does not have a profile.
