ICMP(all) - Filter

This filter permits the “ping” program to be used, for example to check the availability and accessibility of computers
in the Internet and to measure the transfer time of IP packets to these computers. This can be useful, for example, for
locating the server with the most rapid response time for Internet games. When you activate this filter you can also
reach the router using the “ping” program, but not any computer in the LAN “behind” (i.e. downcircuit) of the rou-
ter, as these are protected by NAT. This filter enables all ICPM protocols, and not only those used for »ping«. If neces-
sary you can set further restrictions for this filter by having only ICMP protocols 0 and 8 enabled (echo-request,
echo-reply). Overall security is increased when you do not activate this filter, as the firewall can not be easily located
by a simple »ping« from a port scan program.

SSH - Filter

This filter permits the use of the 443 service programme on computers in the Internet by enabling packets to port xxx
for outgoing connections and incoming packets from that port to non-privileged ports.

TELNET - Filter

This filter permits the use of the telnet service programme at computers in the Internet by enabling packets to port 23
for outgoing connections and incoming packets from this port to non-privileged ports.

P2P - Filter

This filter allows peer-to-peer (P2P) file sharing software to be used. The following ports are enabled to provide one
single filter for the various P2P systems:

Incoming packets:

·

from port 80 to non-privileged ports

·

from port 1214 to non-privileged ports

·

from non-privileged ports to port 80

·

from non-privileged ports to non-privileged ports

Outgoing packets:

·

from non-privileged ports to port 80

·

from non-privileged ports to port 1214

·

from non-privileged ports to port 4661

·

from non-privileged ports to non-privileged ports. With this filter the firewall is wide open!

Gaming - Filter

·

Use this filter to play Internet games. The following port enables have been provided:

Incoming packets:

·

from port 7002 to non-privileged ports for TCP from non-privileged ports to non-privileged ports for UDP

Outgoing packets:

·

from port 7002 to non-privileged ports for TCP from non-privileged ports to non-privileged ports for UDP
