3) Select a port number to use that you can open up on the firewall. If you wanted, you could simply use the last port used when the ARLM was started. You can find this by searching the <accurev_installdir>/storage/site_slice/logs/rlm.log file for the last instance of "accurev on port" line which will have the last port number used for the ISV.
5b) If running AccuRev 6.1 or later: ISV accurev port=isv-port#
The line will look something like this: ISV accurev port=49156
6) In the <accurev_installdir>/extras/unix directory is a script called "accurev_rlm". Edit this script, changing "/sbin/sh" to "/bin/sh" and adjusting the variables to match your installation paths.
