I am setting up a very simple PA200 implementation and all I need at this stage is to be able to contact the Palo update server to update the PanOS. I have the FW plugged in directly from ethernet1/1 to the modem (subnet 192.168.0.1). The gateway is pingable. My machine is connected to the the management interface (172.16.30.35). I have virtual router configured to send all traffic (0.0.0.0/0) out of ethernet1/1. I have an any/any security policy set. I have a NAT rule (I suspect this is the problem) configured to translate the networks to each other (at least that's my intention). I know the issue is something simple but I can't get past it. Any help would be appreciated.

So currently probably the firewall or at least the default-vr has internet access but not your management interface as this one is conected to your computer. The route table of the management plane is completely separated from other dataplane configurations (all the actual firewallinterfaces). In a default configuration the firewall tries to reach everything from the management interface which means the firewalls tries to download updates for example over your computer. I see now two possiblities
In your situation I propose to use possibility 2 and change the sourceinterface for the services that require internet access. If you do this, then a firewallpolicy is required to allow that traffic but as you already have an any-any-allow rule this shouldn't be a problem.

Is your intention to make the PA-200 sit at the edge of your home network? Assuming that this is the case, your NAT statement as presently configured doesn't really make much sense unless you have a route on your modem/router (assuming you aren't talking about an actual straight modem) combo unit pointing back to your firewall. Otherwise you wouldn't have a return route pointing the traffic back to your firewall.
Generally for a home setup your NAT statement would simply have your source-translation setup like so:
Translation Type: Dynamic IP And Port
Address Type: Interface Address
Interface: ethernet1/1
IP address: None (Assuming DHCP assignment, otherwise you can select the static address from the drop down)
What this will do is simply NAT all of the traffic through the address assigned to your ethernet1/1 address and out through the modem. This then allows your modem to know where it has to return the traffic without any additional route configuration.

also... have you really put your external interface into the trust zone? if not then perhaps the NAT destination should be "untrust"

Thanks for your help. I have updated the NAT statement as such. I'm still not getting internet connectivity, though. What other information do you need for us to continue troubleshooting?
Thanks for pointing that out. I have made that correction as well.

Hi,
can you share me route table output.
you can use below steps to get it.
>network > virtual Routers><vr-name> >more runtime stats
And also try to test ( internet, security policy, ping etc) from below step.
