See extract from Windows 6.0 VVR admin guide:

About specifying network ports for replication
VVR uses the UDP or TCP transport protocols for replicating data between the
Primary and Secondary. This section lists the default ports that VVR uses for
replicating.

Port numbers used by VVR
VVR uses the following ports by default.
You must therefore keep the following ports open:
■ Port 4145 (TCP/UDP) is the VVR connection server port
■ Port 8199 (TCP) is the configuration server port
■ Port 8989 (TCP) is the default port used by vxrserver
■ Port 2148 (TCP/UDP) is the VEA server port

Ports for replicating over firewall
VVR can be configured to replicate across a firewall by specifying the data ports
that need to be used. This provides additional security for VVR. The vrport data
command with the port high and port low parameters enables you to configure
the data ports to be used for replication. Use these parameters to specify a range
of ports to be used for replication.

See “Displaying and changing replication ports using the vrport command”
on page 320.

Hi Sally,

In addition to the ports that Mike mentioned, VVR also uses a range of data ports.  If you run "vrport" it will show you what ports VVR is currently using.  By default the data ports should be "0-0" which basically means that VVR does not care what ports are used.  You can use the "vrport" command to set a range of data ports for VVR to use and then you will need to allow those ports through your firewall.  Depending on the rlink settings these data ports can be either UDP or TCP.

Thank you,

Wally

Where should i run that command?

Hi Sally,

You should set the ports for VVR to use for data transfer on both the VVR primary and VVR secondary servers.

 

Thank you,
