[omniORB] Omniorb - working through firewall question

[Jayaraman, Thirupurasundari]

Hi All

We are using omniorb 4.0.7 for a client / server application and we have
used endpoints with ports, so that it can help communicate across
FIREWALL.

We would like to restrict all CORBA ports to a range of 2800 - 2900. 

Recently this solution failed to work in a particular customer site
because they blocked all source and destination ports outside the range.

We configured a network firewall, blocked all destination ports except
2800-2900.

We see that CORBA is using RANDOM Source ports.

Given below is the output of the FIREWALL Log.

Date	Time	Action	Source	Destination	Duration	Bytes
Sent	Bytes Received	Application	
2/27/2012	6:28:32	Permit	192.168.1.11:50368	172.16.1.11:2809
1799 sec	950	791	TCP Port 2809	
2/27/2012	5:51:04	Permit	192.168.1.11:50983	172.16.1.11:2809
121 sec	1090	861	TCP Port 2809	
2/27/2012	5:48:48	Permit	192.168.1.11:50979	172.16.1.11:2809
85 sec	1090	861	TCP Port 2809	

We are trying to reach a destination 2809 and we are using the PORT as
part of endpoint, but we see internally, source ports > 50000 are being
used.

Is there a way we can control source ports?


Regards
Sundari.
