Hello everyone. I am new to Palo Alto firewalls. We have bought many new PA-440's and I am having trouble with my very first installation.
I have a site that is currently using a TP-Link AX1500 router.
Very simple setup.... ISPmodem----WANportOfAX1500/LANportOfAX1500----Clients.
I have tried, without success, to mimic the setup of the AX1500 and replace it with the PA-440. I have the PA-440 acting as a DHCP server. My clients get IP addresses, and then can ping the PA-440. They cannot ping anything on the Internet. From the PA-440 command line, I also cannot ping anything on the Internet (ping host 18.104.22.168 for example).
I know this post leaves many questions, but is there a guide on a very basic setup like this? I am sure I am missing something small but have been unable to put my finger on it.
Thank you -- Walter
"ping host 22.214.171.124" sends ping requests out from Palo mgmt interface.
For this to work mgmt interface needs to be connected, NAT and security policy need to be in place.
Do you see those sessions under "Monitor > Traffic"?
By default "interzone-default" and "intrazone-default" rules don't log so it is suggested to override them and check "Log at session end" on Actions tab.
You can also try "ping source 126.96.36.199 host 188.8.131.52" (replace 184.108.40.206 with your WAN IP).
In this case ping goes out from WAN interface. NAT is not needed and by default "intrazone-default" rule will permit this traffic.
If you share output of your results we can help you get them connected.
Thank you very much for responding.
I am now working on the bench in my office. I have two Windows laptops, one Windows PC, and the Palo.
I have attached a picture of the connections.
I am sure I am missing something fundamental.
If you don't specify source IP (like ping host 10.10.150.51) then ping requests go out from mgmt interface.
There is no interconnection inside firewall between mgmt port and dataplane port.
For mgmt port to have connectivity you need to connect fw internal interface and mgmt port into switch so they can see each other.
You don't appear to be logging your interzone-default policy, for troubleshooting I'd enable that so you can ensure that the traffic is actually being processed properly and isn't getting dropped. Couple things I would look at:
