Tools
There are three tools in the Network|Tools menu to help you test the network connections and
RouteFinder functionality. Ping and Traceroute test the network connections on the IP level.
The ICMP on firewall function in the Packet Filter|ICMP menu must be active for these tools.
The TCP connect tool tests TCP services for availability.
All three tools contain the additional function Name Resolution. It makes sure that the IP addresses of
the return packets are converted into valid names. For Name Resolution to work, the DNS proxy
function in the Proxies|DNS menu must be enabled.
Ping
Ping lets you test the connection to a remote host. The program Ping sends an ICMP echo packet to a
different computer. When the computer receives the ICMP echo packet, its TCP-IP-Stack must send an
ICMP reply packet back to the sender. This lets you check whether a connection to another
network computer is possible.
The Ping command checks the connections to a remote host using ICMP Echo Request and Reply
packets to determine whether a certain IP is reachable. You can enter the IP address as well as the
name of a host.
Note: For the Ping tool to function, the ICMP on firewall function in Packet Filter|ICMP must be
enabled.
Note: For the Name Resolution function, the DNS proxy function in Proxies|DNS must be enabled. To
use the Name Resolution function, a name server in the menu (item) Proxies|Nameserver must be
enabled. With Name server enabled, the IP addresses of the reply packets will be converted into valid
names.
