Problem with NAT rules

Hello

Task is simple, give access to 3 IP from Internet to camera on non-standart ports. Ports and  local IP are:

192.168.220.251:554 -> x.x.x.x:554

192.168.220.251:80 -> x.x.x.x:8881

192.168.220.251:8554-8557 -> x.x.x.x:8554-8557

where x.x.x.x is one of IP belongings for my PA and is used for NAT from this zone to untrust.

I created security rules:

and NAT rules:

2014-05-20_174055.png

but it doesn't working. For first step I'd like to test port 80 redirection.

So I try to change something. When I remove 8881tcp from security number 14 I'm able to open web page of IP camera using x.x.x.x:80.

Please tell me where is my mistake?

With regards

Re: Problem with NAT rules

When creating a Inbound NAT make sure that you source address is the address of where the traffic is coming from. In this case of the camera.

Your destination address is the public interface IP on the palo alto firewall.

Since you have them hidden and not described in the above question not sure if that is what you are doing. Please confirm that.

Following document from page 15 explains different destination NAT scenarios.
