GlobalProtect Pre-logon tunnel rename doesn't work as expected

L1 Bithead

Hi Guys,

 

We are currently running PanOS8.1.1 have some issues with global protect pre-logon. I have configured pre-logon as per below article.

Problem we have is pre logon works as expected, however when user logged in to the computer, pre logon tunnel getting disconnected and connecting again with user logon.

 

What we want is prelogon tunnel to be renamed so for user vpn stays connected ater logged in

Hmmm, this sounds possibly like what we saw when we tried to upgrade to 8.1.1 all of our VPN users got dropped and the ones that could reconnect showed as pre-logon instead of their user names and they kept getting the authentication popups from the GP client. we ended up rolling back and have an open case with PA now

 

expected behavior was:

pre-logon connections is up->user logs into windows->VPN tunnel switches to user authenticated and pre-logon goes away

was there ever a resolution for this? I am currently experiencing the same issue with 8.1.13 and GP 5.0.8

I had a very similar issue with pre-login (always on) connections, tunnel rename, and RADIUS-based MFA. Our portal login profile only requires username/password, but our gateways require MFA. We also had the "pre-login tunnel rename timeout" set to the default of -1 and users were experiencing all sorts of problems connecting after login.

 

Setting the pre-login tunnel rename timeout to 0 solved it (since you're requiring MFA during gateway login, there's no point in renaming the tunnel). So users are re-prompted for credentials and the MFA passes correctly.

 

I don't know if tunnel rename is supposed to work with MFA gateways and pre-login, but intuitively it really should not. PA's guidance seems to be only set the timeout to 0 when using pre-login then on-demand, but with MFA, I don't think the tunnel rename actually works correctly.
