Global Protect unable access certain vm behind firewall

L1 Bithead

Hello Folks.

 

So we have configured GP in one VM-Series in a Cloud Community. We are experiencing unusual behavior. I do not know whether it was the GP configuration or it is in the VM. So sample VM 1 has an IP of 192.168.14.X  and VM 2 has an IP of 192.168.14.X when connected in GP I can ping VM1 also the traceroute is complete but when trying to reach VM 2 is shows RTO and it is not reachable via traceroute. When looking into the firewall logs it show that the the traceroute is allowed going to VM 2 with an application of traceroute, also it hits the right rule. 

 

Thank you for your answers if you replied.!

Found the problem here. Never assign any network for GP that has the same segment as an interface of a vm that is behind the firewall.

@vtlikinio,

Does the other VM have a route back to whatever IP space you are using for GlobalProtect clients? If you take a packet capture on the unreachable VM does it show traffic hitting the VM from GlobalProtect clients?

Yep, just took PCAP just now the GP reaches the ping but the server does not response back.
