Mac connected in VPN doesn't work

L3 Networker

Hi Guys,


customer connected a Mac (OSX 10.13.2) using global protect and other vpn client (native and cisco), but i can't reach a remote server.


Doing a packet capture i found the PA (pa-3020, 7.1.14) doesn't forward the reply packet.

[Mac]--------->[PAN]--------->[Server]        OK

[Mac]               [PAN]<---------[Server]        PAN stops return traffic


i thought it was a problem caused by a third-party vpn client, but they told me the same issue is present when GP is used, but they told me all problematic users use a Mac.


Do you have some hints?

What do the logs show when you filter them sourced from the MAC's IP address to the destination servers IP?


Might give some clues.

Hi Mate, 


Using Macs with gp - 10.13.2 and gp clients 4.0.5-8. Have no issue connecting through GP and reaching remote servers when working from home. Connect to multiple different gp networks regularly from mac, and servers over rdp of https type connections.


Out of interest, if ye block udp4051 connections, so the tunnels established as ssl, do ye have the same issue ?

As always if causing a production impact open a case with your support partner.
