POrt forwarding / Trigger?

Hi ,

  I have a sittuation where I'd like soft phone clients to work from a public IP addressing space without having to traverse our VPN.  As such I want to see if I can have our SRX device forward incoming requests from it's outside interface to an inside IP address based off of the destination port. 

 

Will this be possible?

If I really understand your need, yes it's possible to do a nat destination based on the destination port.

 

You have to configure the public IP adress on your SRX with a proxy-arp.

Then, just write the destination nat rules corresponding to this adress and a destination-nat pool with the port needed by your application.

Any chance you could elaborate on the nat pool for this type of configuration?

 

And, thank you for the response. :smileyhappy:
