Filtering

The IP Filtering Setup dialog provides tabs that let you configure the ProxyServer so that IP

packets that are received by the server can be selectively filtered or forwarded based on their

addresses or by the protocol ports to which they are destined.

The three filtering methods are:

• IP Protocol Port Based Filtering - In this method, IP packets can be filtered based on their

specific purposes; e.g. Telnet packets (TCP based) or TFTP (UDP based) can be filtered or

forwarded.

• IP Address Based Filtering - In this method, filtering is based on the source and destination

IP addresses in the packet.

• ICMP Filtering - Separate filtering support is provided for specific kinds of received ICMP

packets.

For a more detailed description of filtering, refer to the on-line help provided with your Firewall

software.
