Firewall
When configuring an FCIP route in a WAN containing a firewall, the TCP and
server ports used by the FCIP route must be unblocked. Table 5-3 lists the
well-known ports and server ports that require unblocking in the firewall.
To verify the listen port number, run the following command (from a Linux system),
where the IP address specified is that of the remote router’s management port:
rpcinfo -p <IP address>
Look for the following program numbers:
