All other packets will be Accepted. Example 2: Filter Name: Out_Filter2 Protocol: UDP Source IP Address: 192.168.1.45 Source Subnet Mask: 255.255.255.0 Source Port: 5060:6060 Dest. IP Address: 172.16.13.4 Dest. Subnet Mask: 255.255.255.0 Dest. Port: 6060:7070 This filter will drop all UDP packets coming from the LAN with IP Address / Subnet Mask of 192.168.1.45/24 and a source port range of 5060 to 6060, destined to 172.16.13.4/24 and a destination port range of 6060 to 7070.

By setting up one or more filters, specific packet types coming from the WAN can be Accepted. Example 1: Filter Name: In_Filter1 Protocol: TCP Policy: Allow Source IP Address: 210.168.219.45 Source Subnet Mask: 255.255.0.0 Source Port: 80 Dest. IP Address: NA Dest. Subnet Mask: NA Dest.
