block-ip-frag Block IP Fragments

Checking this option will protect your network from a common type of

hacker attack that could make use of fragmented data packets to

sabotage your network. Note that VPN over IPSec and some UDP-

based services make legitimate use of IP fragments. You will need to

allow IP fragments to pass into the home network in order to make use

of these selected services.
