I am having an issue with one way audio. We are using Secure Remote for a vpn client and when we use IP communicator the audio flow is one direction. If I call an external number the remote party can hear me but I can not hear the remote party. This is the same using the Cisco VPN client as well.

I have a Security Engineer looking through the logs but he can not see why RTP is being dropped. We have had this same issue trying to get the siemens soft phone to work. My firewall has inbound NAT setup could that be causing the drop in the RTP packets because the firewall is seeing a different IP address. What rule should be setup in the Checkpoint firewall?
I have had the Security engineer looking into this for 2 days now but he is not sure of the resolution.
What version of CP you using bud?
Also, I would set up the VoIP system using the VoIP domains as per the CP manuals as the domains, when set up correctly, will basically open up the the dynamic ports required for the RTP stuff. Its to do with the SIP/H323 ALG and letting CP know which ports it needs to open dynamically.
In this case, cos it will be really difficult to troubleshoot over EE, I would raise a case with CP to get this resolved quickly.

Double check your logs bud, cos one way VOIP traffic normally means a firewall is dropping one side of the comms.
You may be allowing the control traffic through to set up the call, ie SIP or H323, but the actual media, the RTP is being allowed through out your firewall, but the return traffic is not
being allowed.
Your logs willgive an indication of what rule is being hit and also what the drop reason is.
