To configure TCP/IP rules, select TCP/IP Filter Rule from the Filter Type field and press [ENTER] to open Menu 21.1.x.1 - TCP/IP Filter Rule, as shown next.

Filter Type Use [SPACE BAR] and then [ENTER] to choose a rule. Parameters displayed for each type will be different. Choices are TCP/IP Filter Rule or Generic Filter Rule. Active Select Yes to activate or No to deactivate the filter rule. IP Protocol This is the upper layer protocol, for example, TCP is 6, UDP is 17 and ICMP is 1. The value must be between 0 and 255. A value of 0 matches ANY protocol. IP Source Route IP Source Route is an optional header that dictates the route an IP packet takes from its source to its destination. If Yes, the rule applies to any packet with an IP source route. The majority of IP packets do not have source route. Destination: IP Addr Type the destination IP address of the packet you want to filter. This field is ignored if it is 0.0.0.0. IP Mask Type the IP mask to apply to the Destination: IP Addr field. 193 Chapter 21 Filter Configuration
