PA VM 6.1.0 Routing issues

Hello Experts,

I am stuck with a Palo Alto test setup. I have a 6.1.0 VM version running on VMW. I have simulated the inside interface by a 10.10.0/24 subnet—- the two hosts are a **bleep** Small Linux with IP 10.10.10.190 (/24) which is connecting to the PA VM Ethernet1/1 L3 interface with IP 10.10.10.200 (/24).

 

VMnet2 is used for managment interface and has the IP 192.168.1.1/24 and I am using this to connect to the PA VM GUI

The outside interface is simulated by a VMNet (8)adapter which is in a shared mode with Physical Ethernet NIC. The subnet of VMNet8 is 192.168.137.0/24. The Palo alto interface connecting to VMnet 8 is Ethernet1/2 and has an IP 192.168.137.200(/24). The VmNet8 adapter has the IP 192.168.137.1(/24).

 

I have configured a default route on the PA VM with proper interfaces and virtual router and the default routes next hop is 192.168.137.1. When I am trying to ping 8.8.8.8 it shows me an unreachable response from the management interface (192.168.1.1)

Please help

 

Following are some outputs from the device :

Re: PA VM 6.1.0 Routing issues

@Sankhya1012,

1) I wouldn't start working with a 6.1.0 install at this point. You really should be using a modern version of the OS and perform an update to the latest maintenance release if you are deadset on staying with 6.1. 

 

By default if you just run the 'ping host 8.8.8.8' command you would be sent out the management interface, so try running the command with 'ping source whatevertheoutsideIPis host 8.8.8.8' and see if you get a response. Also keep in mind that you need a security policy that allows this traffic to take place.  

With a quick glance I'm not seeing anything where you are actively giving the management interface a way outside the network.

@BPry

 

Thank you for the response. I am pretty new to this [only 3days and still failing to setup the lab] , getting used to a lot of things. I have switched to 8.0. Same setup. The egress interface or the Internet facing interface is sharing internet connection with my Physical intel NIC of the PC. I have tested this "sharing " by using a D Small Linux and it can reach the internet just fine.

 

Through Palo Alto however , its not working. I have broken it down into the following parts. Really appreciate the help
