#Globalprotect vpn client how to#
None TalkTalk customers would need to Google for how to change their MTU size but again you do so at your own risk. Low and behold this seems to have made her laptop significantly more stable and connectivity back to the council network seems normal.įor those who are a bit tech savvy and want to try this logon to your routers admin page, enter the admin credentials found on the back of your router, then Settings > Internet (WAN) > Advanced Settings > MTU: 1432 is the default so change to 1500 > click the bottom of the two Save buttons, then give your laptop a reboot and retry. GlobalProtect is using an IPSEC VPN which will add additional encapsulation to the frame sizes, so I upped the MTU size to 1500. Looking at the config of the WAN interface on the router, the MTU size defaults to 1432. What I did notice was that the GlobalProtect app was reporting quite a large number of dropped inbound packets. Tethering her laptop to her phone worked fine. I tried the usual of relaxing the firewall protection on the 3782 router along with enabling UPNP, port forwarding and also putting her laptop in the router's DMZ all to no avail. Extremely slow logons to Windows and as you'd expect poor performance when using applications, email, council intranet and with regular connection drops inside the GlobalProtect application. My wife works for a council in Yorkshire who have recently rolled out the Palo Alto GlobalProtect VPN client and since then she has experienced horrendous problems with connectivity into the council network.
