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. Smiley Happy
