I'm using a Cisco ASA 5510 and have a conneciton that needs to establish from the inside to the outside of the network. The issue is the destination for the traffic requires a static source port for the traffic due to their company security policy. Our appluication sourcing the traffic uses a random port when generating the traffic starting from 1024 to 65535.
I have prevously configured a linux box to to such a task where it changes the source port to the required value. I am wondering if anyone has a confiugration example on how I could do this in an ASA usign either 8.2 or 8.3 ASA software.
the flow is below
192.168.136.16 (random source port) -------> ASA 5510 ---------> DEST IP (126.96.36.199) TCP port 2365
I need the source port to be 4000 as it leaves the outside interface of the ASA. The outisde interface of the FW (10.1.4.190) is used when NATing the address I could however change this to a specific global address.
Any help would be appreciated.
