Customizing the data port range for remote connections

5 If you want to connect through pcAnywhere Gateway or Access Server, check
Connect through Gateway or Access Server.
See "Connecting through a pcAnywhere Gateway or an Access Server"
on page 105.

On the Settings tab, type the IP address or computer name of the computer
to which you want to connect.
You can leave this information blank. When you start the session, pcAnywhere
will automatically search your subnet for available hosts. This process can
be time-consuming if your computer belongs to a large network.

Click OK.
Administrators can customize network settings to handle connections on both
sides of a firewall.
Symantec pcAnywhere automatically chooses a port number each time that you
make a remote connection. For security or performance reasons, an administrator
might want to limit the number of ports that are used for outbound connections.
Limiting connections to too small a range can cause connections to fail because
there might not be enough available ports.
Note: Some port numbers lower than 1024 are reserved for Web-based applications
and services, such as FTP and the Internet. Choosing a reserved port number
might interfere with these applications and possibly result in loss of service. This
procedure should be performed by an experienced administrator.
To customize the data port range for remote connections
1
In the Symantec pcAnywhere window, on the Edit menu, click Preferences.
2
In the pcAnywhere Options window, on the Remote Communications tab,
click Advanced TCP/IP Options.
3
In the Advanced Remote TCP/IP Options window, check Specify outbound
data port range.
4
In the Base data port box, type the port number of the first port in the range.
5
In the Size of range box, type the number of ports to be used in the port range.
Adding this number to the number that you entered in the Base data port box
determines the last port number in the range.
