Rules Menu Options
Use the Options checkboxes to enable the following:
Enable VPN Passthrough (IPSec, PPTP, L2TP) 
If LAN users need to use VPN (Virtual Private Networking) software on their computer, and 
connect to remote sites or servers, enable this checkbox. This will allow the VPN protocols 
(IPSec, PPTP, L2TP) to be used. If this checkbox is not checked, these protocols are blocked.
Drop fragmented IP packets 
If checked, all fragmented IP packets will be dropped (discarded). Normally, this should NOT 
be checked.
Block TCP flood 
If checked, when a TCP flood attack is detected, the port used will be closed, and no traffic 
will be able to use that port.
Block UDP flood 
If checked, when a UDP flood attack is detected, all traffic from that IP address will be 
blocked.
Block non-standard packets 
If checked, only known packet types will be accepted; other packets will be blocked. The 
known packet types are TCP, UDP, ICMP, ESP, and GRE. Note that these are packet types, not 
protocols. 
Setting Times and Scheduling Firewall Services
The FVS328 Firewall uses the Network Time Protocol (NTP) to obtain the current time and date 
from one of several Network Time Servers on the Internet. In order to localize the time for your 
log entries, you must select your Time Zone from the list.
