Cannot ping interface, IP or defaul gateway from PA 500 to Cisco switch

phugiay — Tue, 03 Jan 2023 23:32:14 GMT

Hi all ,

I set up PA 500 to connect to Cisco layer 3 switch. I cannot ping any website or the IP from PA 500 except the Ip address assigned from Comcast. I look on the NAT, security and virtual routing but nothing wrong.

1. I plug my comcast router to Ethernet1/1 (untrust) and Ethernet1/2( trust) to Cisco switch. PA picked up the DHCP Client (10.0.0.126)( I can ping this Ip from my laptop when I connect to my internet Wifi) and it shows the IP after I hit Commits and show green light. However, I cannot ping website like yahoo or ip or I cannot ping my wifi at home like Cisco ASA except the IP that Comcast assigned for PA 500. I search from here and everyone said the issue is NAT/security policy/Virtual router. Since this is not a static IP so there is no need for virtual routing (Correct me if I am wrong)

2. My Cisco switch has 2 VLAN 10 (192.168.10.0/24)and 12 (10.33.12.0/24). I assigned IP 192.168.10.50 for PA 500 and from my laptop or server, I can ping PA 500 but not the comcast IP. (something is not right here) For Cisco ASA, you connect one port from ASA to another port from your switch and you route all your VLAN to ASA port and from ASA you route to the port on switch.

I attached the file and my routing. I changed my Management Profile all to ping. I did the screenshot before I change

Raido_Rattameister — Wed, 04 Jan 2023 00:01:15 GMT

I see error "bind: Cannot assign requested address".

Can you share screenshot of popup you get when you click on "Dynamic DHCP Client" link on ethernet1/1?

Hi,

I can be able to ping from my interface with source.

ping 10.0.0.0.125 source 8.8.8.8 or 74.6.143.26 (yahoo.com) but I cannot ping directly the ip or website

For Cisco ASA, this is DNS issue because firewall needs to translate the website to IP and DNS lookup outside and assign DNS will fix the issue and I look DNS proxy and add 8.8.8.8 but it didn't help.

Re: Cannot ping interface, IP or defaul gateway from PA 500 to Cisco switch

Raido_Rattameister — Fri, 06 Jan 2023 15:28:35 GMT

ping host 8.8.8.8 - ping requests go out from management interface

ping source 10.0.0.125 host 8.8.8.8 - ping requests go out from dataplane interface that has IP 10.0.0.125 assigned.

If command ping host 8.8.8.8 does not work it means your firewall management interface can't access internet.

Hi Raido,

So what is the issue? NAT/policy/virtual router? From my laptop with my comcast Wifi, I can ping 10.0.0.125 but from PA 500, I cannot ping my laptop IP.

Re: Cannot ping interface, IP or defaul gateway from PA 500 to Cisco switch

Raido_Rattameister — Sun, 08 Jan 2023 18:02:32 GMT

Does "ping host 192.168.10.1" work? This would ping from mgmt interface to default gw IP.

Have you configured NAT to change 192.168.10.0/24 IP to 10.0.0.126 and security policy to permit trust to untrust traffic?

What is output of Monitor > Traffic if you run commands "ping host 192.168.10.1" and "ping host 9.9.9.9" and use filter below?

(addr.dst in 192.168.10.1 ) or (addr.dst in 9.9.9.9 )

Re: Cannot ping interface, IP or defaul gateway from PA 500 to Cisco switch

phugiay — Mon, 09 Jan 2023 22:28:09 GMT

Yes, I can ping 192.168.10.1 because this is my default GW from DHCP server

I assigned the firewall with the static IP 192.168.10.50 255.255.255.0 192.168.10.1 the same VLAN on my switch so from firewall, I can ping all the desktop and servers and the other way.

Hi ,

I have been OOO and just get back. I can make it work. All about DNS issue like ASA.

Thank you for your time.

One thing,

How do I back up entire config the PA from CLI , not from snapshot? Cisco is all from show run.

Thank you

If it is standalone firewall and config is not pushed from Panorama then you can get config from cli using commands below.

> set cli config-output-format set

> configure
