Help setting up internet connection

Hi there

We're in the process of cutting over to a new internet connection and I'm trying to get our PA 2050 configured to handle to new IP range but I'm a bit stuck. We've been assigned the subnet with being the default gateway.

Currently I've set the external interface to and configured a virtual router with a static route for to Finally I've set an outbound NAT rule of Dynamic IP and Port, address type is Interface Address, interface is ethernet 1/2 (the external interface) and the IP address is but no joy.

I'm basing this config on our existing working config but that one has the default gateway outside the subnet assigned to us. That subnet is and the default gateway is

Any suggestions on where I've gone wrong?


Accepted Solutions

The portions of your configuration that you have posted appear to be correct. You can check the traffic logs to see if the traffic is being translated. From there, you may want to open a case with support.

Do you see the arp entry for the new def gateway.

>show arp all

Yes, first entry in the arp table

interface     ip address  hw address    port     status   ttl 


ethernet1/2   a8:d0:e5:05:2a:41 ethernet1/21142

Can you ping .113 from .112 (you might want to enable management profile for testing).

I can reach from my side.

No can't ping it but in saying that, can't ping the upstream router from the existing external interface and that still works anyway. The management profile is set to allow ping.

Can we try sending out garps on that interface to confirm the correct hw address

There is no deny all policy right?

test arp gratuitous ip interface ethernet1/2

1 ARPs were sent

Still no internet access. I do have a deny all rule at the bottom of my security rules. Checking the network monitor from my test IP,  I can see my traceroute and internet activity being allowed by my Layer 3 External rule.

Any interface errors

show interface ethernet1/2

have you tried changing the cable.

If all of the above does not work please open a support case with us.

Make sure that the interfaces you are sending traffic to and from are both part of the same virtual router. If they are using seperate virtual routers you will need to set up routing between them.

Actually it appears I misunderstood what our ISP set up for us. I received this email from them.

You have been allocated a new subnet We have configured in our core. The rest of the addresses .114 to .126 are available for you to use on your firewall for interface addressing, NAT etc. You will need to change the ip address on the outside of your firewall to one of these available addresses and change your default route to point to next hop

So my question is then, how do I got about setting up my external interface to have the IP addresses from .114 to .126 and what would my outbound NAT rule look like?

Here's some of my current non-functional config
