Question

Fortigate SSL VPN with Duo auto Push

Hello, we are experiencing the behavior noted in this previous old thread. 

 

Re: Fortigate SSL VPN + Duo Security + RADIUS Auth... - Fortinet Community

 

We tried setting "config system global - set remoteauthtimeout" , did not seem to change it for our VDOM where the SSL VPN lives. 

 

Other settings we tried:   set two-factor-fac-expiry and set timeout 300 (the latter in the radius config)

 

Any ideas / help? We opened a case with Duo also

Hey geresont,

to my knowledge, the remoteauthtimeout setting should apply to the VDOM as well.

What firmware version is your FortiGate? I could have a look to see if there are reported bugs for your version and verify if the remoteauthtimeout setting doesn't apply correctly.

The 'two-factor-fac-expiry' and 'set timeout 300' should not apply to Duo Auth, I believe.

 

You can also gather this debug, it might provide some information:
#dia de reset

#dia de app fnbamd -1

#dia de console timestamp en

#dia de en

#dia test authserver radius <RADIUS server entry> <pap|chap|mschap2> <username> <password>

-> this triggers a RADIUS authentication, and debug will be dumped showing FortiGate contacting the RADIUS server.

There should also be an indication when a timeout is declared.

There are a lot of obscure numbers and error codes, but if you copy the output to a file (or log it to a file) you can search for 'timeout' or the radius server IP; there should also be something like 'received auth request <ID>', and you can use that ID to find the beginning and end of the auth request; the timestamps will let you know how long the FortiGate waited.
