Forward UDP 3290 through ASA5505

I need to forward UDP port 3290 from the outside of my network to any host on the inside interface.

The application is a primitive voice protocol, whereby the client communicates to the server via TCP which port should be used for UDP communication.  The server then starts sending UDP packets on that port towards the host.

 

Since my machine uses DHCP to acquire its address, I would prefer not to have to allow the UDP to only a single host, but I could do so if that's the only solution.

 

Can someone give me an example of allowing this traffic via CLI?

Hi, I am not really sure

Hi,

 

I am not really sure about how the setup is. Are you talking about a setup where you have internal users behind an ASA and the server is located somewhere on the Internet?

 

I don't really think its possible to achieve this in that kind of setup as you are probably doing Dynamic PAT towards the external network and you naturally can't forward a single port of a single public IP address to multiple internal host.
