Protocol-list

This list permits data packets to be blocked or released according to the protocol used (the type of action depends on the setting of the positive/negative switch).

Each Ethernet frame contains a 16-bit identifier for its layer-3 protocol. These can be entered in the list as hexadecimal numbers.

The hexadecimal identifiers for the most important layer-3 protocols as per RFC 1010:

0800 Internet Protocol - IP (IPv4)
0806 Address Resolution Protocol (ARP)
8035 Reverse ARP
809B AppleTalk
80F3 AppleTalk Address Resolution Protocol (AARP)
8137 NetWare IPX (old, with 'ECONFIG E' option)
8138 NetWare IPX

Note: Again, this only denies stations access to the LAN or WAN; data communications between stations in the WLAN is unaffected.
