Packet Filtering
Issue 4 May 2005 185
What can be filtered
Table 10 lists the specific types of traffic that can be filtered.
Packet Filtering and NAT
Network address translation (NAT) and packet filtering services can be run simultaneously.
Depending on the direction of the traffic, the VSU automatically determines which sequence the
services will run.
For inbound packets (to the WAN), NAT is run first, then filtering. For outbound packets, filtering
is run first, followed by NAT.
