Cant access Global protect vpn through vodafone dsl

[himanshu.3333]

Hi Team, I am using vodafone dsl connection. Recently i joined a new company and have to use global connect vpn. somehow the vpn does not works from my vodafone wifi. 

I checked with my office folks and looks like the issues is from vodafone dsl side. now vodafone assign ipv4 through ds lite and have ipv6 public address

I asked them this may  be a issue related to assigning me more ipv4 address and they are signing everyone is on ipv6, ipv4 is 25 years old technology.

I also tried to reduce the MTU to 1200 and did all trouble shooting steps.

Please help me hpw do i access global protech vpn as my work has stopped now. If my isp needs to provide solution tell me what needs to be done

MTU you have already tried try disabling IPV6 on your laptop completely. It sounds more of ISP issue.

Hello,

We had a similar issue for one of our employees who uses a Vodafone connection.

We fixed it for him by setting a fixed MTU size in the App configuration:

"GlobalProtect Connection MTU (bytes)" set to 1300

MTU thing did not work 😞

Hello,

Did your IT staff change that setting for you in their global protect configuration on their firewall or did you try to change the mtu size on your local pc? My suggestion concerns a change in the global protect configuration on the firewall!

Normally reducing MTU should fix the issue. Where did you change the MTU locally on the client or GP portal configuration? It should be changed on the portal.
