GlobalProtect Clients fall back to SSL

Hi,

 

Our GP Clients initially try to establish a connection over IPSec, but fall back to SSL every time. I can see the IPSEC traffic coming in and being allowed and do not know how to find why the tunnel is not establishing over IPSec.

 

Any ideas on how to troubleshoot this? Or suggestions?

 

Thanks,

Shannon

If we (firewall) have sent the reply traffic correctly, and it doesn't make to the client, it's possible it's blocked by the ISP. Are all the clients (coming from different ISPs) having the same issue?

Hi Ansharma,

 

Thanks for your reply. It seems to be a very high number of clients, and yes they are over different ISP's.

 

Thanks,
Shannon
