Resolution:
1. If you need to configure RVRD with firewall:

              |
   RVRDA      |      RVRDB
              |
   ____               ____
    DMZ   Firewall  Secure
                   Inner net



IP.A.dmz: box A ip address seen from DMZ network
IP.A.internal; Box A ip address seen from Internal network

IP.FW.dmz
IP.FW.Internal

IP.B.dmz
IP.B.Internal



-- If you use a passive or accept any configuration (I will advice to use
passive instead of accept any) with a local port XXX on the rvrd in the
"Secure inner net", you should configure the firewall to authorize TCP
connection from the rvrd in the DMZ to the rvrd in "Secure inner net" using
destination port XXX.

-- If you use a active or seek any configuration with a remote port XXX on
the rvrd in the "Secure inner net" you should configure the firewall to
authorize TCP connection from the rvrd in "Secure inner net" to the rvrd
in the DMZ using destination port XXX.


-- when you config "Remote Endpoint" host, RVRDB should use IP.A.internal and
RVRDA should use IP.B.dmz.



2. We are not firewall expert, so that if you still have the problem,
please discuss this with your admin, and also

-- please run "netstat -a" from firewall box, and send us the results for review.

-- Firewall version

-- compare the firewall configurations with the one which is working and find out the difference.

-- also verify the port used for the communication is configurable. some applications only
use specific port, other ports will not work.
