IP Firewall

InfiNet Wireless IP Firewall is a mechanism of filtering packets crossing an IP network node, according to different criteria. System administrator may define a set of incoming filters and a set of outgoing filters. The incoming filters determine which packets may be accepted by the node. The outgoing filters determine which packets may be forwarded by the node as a result of routing or switching.

Packets can be filtered based on the following criteria:

• Protocol (IP, TCP, UDP, ICMP);
• Source address and/or destination address (and port numbers for TCP and UDP);
• The network interface it arrived on;
• Whether the packet is a TCP/IP connection request (a packet attempting to initiate a TCP/IP session) or not;
• Whether the packet is a head, tail or intermediate IP fragment;
• Whether the packet has certain IP options defined or not;
• The MAC address of the destination station or of the source station.
