When configuring pcAnywhere to work across a firewall, additional ports may need to be opened to allow pcAnywhere to authenticate.
Symantec pcAnywhere uses two standard ports for communication: 5631 TCP and 5632 UDP. If authentication other than pcAnywhere Authentication is utilized, however, the ports required for those methods of authentication to contact the appropriate network services may also need to be available when authenticating across a firewall. pcAnywhere makes a call to the appropriate Windows API to pass authentication to the appropriate resources. Below is a list of several methods of authentication and the associated ports used by their APIs.
Windows authentication with a user account on the domain utilizes the following ports: 1025 137 53
Windows NT authentication with a user account on the domain utilizes the following ports: 1025 445 389 137 88 53
ADS authentication with a user account on the domain utilizes the following ports: 1025 445 389 137 135 88 53
HTTP authentication with an HTTP account utilizes the following ports: 80
HTTPS authentication with an HTTPS account utilizes the following ports: 443
FTP authentication with a FTP account utilizes the following ports: 20
Microsoft LDAP caller authentication utilizes the following ports. 389 137
This list is subject to change as the authentication API's that pcAnywhere call upon change.
