What are the ports needed to be kept open on WEBppliance server for What are the ports needed to be kept open on WEBppliance server for Extend to perform any kind of operation.

The following ports need to be kept open on WEBppliance server for the extend to register or perform any other operation on the WEBppliance server:

19635/tcp - For Extend to contact webppliance
22/tcp - SSH
21/tcp - FTP
20/tcp - FTPDATA

Extend contacts the WEBppliance server using ssh on the port 19635. If the ssh deamon is not active on the port 19635, extend will fail to perform most of the operations on that WEBppliance server. You can make sure that ssh daemon on WEBppliance server is listening on port 19635 by starting the ssh-rb service daemon on the webppliance server using following command:

/etc/rc.d/init.d/sshd-rb start

FTP ports need to be open to allow site moves from one server to another. If those ports are not open, all functionality will work except for Site Moves.
