So PPP LCP part of he negoiation is failing. This could be any of the following;
AUTHEN type ( chap pap msChap )
So I would double check the above and roll thru the available authtype if you believe the username/password are correct;
e,g ( would set pap for dialup#1)
config sys modem
set authtype1 pap
If that doesn't work, try the 3g-modem on a none 51E and see what happens. If I recall correctly, the pecking order is pap and than chap and mschap use a ? mark to see the options and ordering. Fortinet has made some changes in this area depending on model and code from iirc.
Good luck with this. We struggled with USB modems directly into the Fortinet's for over a month before realizing that this is the single worst aspect of Fortinet IMO. Now we use Cradles if we want to interface a USB with a Fortinet.
Even Fortinet support finally gave up back then on us. My advice is to not even try.
I am struggling to get a USB 3G/4G Modem (Huwaei E3276) to work. The FGT-51E does recognize the modem and I can set it up in a way that is starts dialling, but I never get a connection.
If I use the modem on my PC with the exact same settings (same APN, username and what have you), I have no issues.
Has anyone ever gotten this to work?
Here is what I get in a debug output while the modem is dialling:
We will see. I have a support ticket open with them and will have a call with them tomorrow afternoon.
As for the different authentication schemes, Ken, my understanding is they are all enabled and the box goes through them until one matches or whatever is negotiated. I might be wrong, but this is what the default config looks like if you are not tampering with the auth config:
To me it "feels" like it is dialing but never getting a response, but the logs and your observation, Ken, speak a different language. It's most likely something during the PAP/CHAP negotiation that goes wrong.
I'll try setting authtype explicitly and try each of them.
