You can change these defaults if you like but this is from Symantec's site:
The pcAnywhere use of IP ports changes with the version of pcAnywhere used. Earlier versions used ports 22 (UDP) and 65301 (TCP). These ports were not registered. Beginning with version 7.5, pcAnywhere uses the ports 5631 (TCP) and 5632 (UDP). These ports are registered with the Internet Assigned Numbers Authority (IANA). The following is a brief summary by version:
pcAnywhere 9.2 and pcAnywhere 10.x use ports 5631 and 5632 only.
pcANYWHERE32 8.0 and pcAnywhere 9.0 use ports 5631 and 5632, but it will fall back to 22 and 65301 if no hosts are found on 5631 or 5632.
pcANYWHERE32 7.5 uses ports 5631 and 5632.
pcANYWHERE32 7.0 uses ports 22 and 65301. A download file can change port usage to 5631 and 5632.
pcANYWHERE 2.0 uses ports 22 and 65301. With version 2.03 and higher, a download file can change port usage to 5631 and 5632.
