In Fedora 25 + Cinnamon, it looks like this by default.

I wouldn't use any of those authentication protocols except MSCHAPv2... uncheck the rest of them.

He is just showing the options on Fedora, as I'm trying to figure out a weird setting recommendation by Cisco to "require encryption" when using PAP and IPSEC.

It's several posts above this. . . might be worth its own topic.

@DustinB3403 here is my home ERL.

The part that is going over with Unencrypted PAP is testuser/Testing!123.
But it is going over the Existing IPSEC tunnel that was set up with the PSK.

jbusch@jared:~$ show configuration commands vpn | grep l2tp
set vpn l2tp remote-access authentication local-users username testuser password 'Testing!123'
set vpn l2tp remote-access authentication mode local
set vpn l2tp remote-access client-ip-pool start 10.254.203.2
set vpn l2tp remote-access client-ip-pool stop 10.254.203.10
set vpn l2tp remote-access dhcp-interface eth0
set vpn l2tp remote-access dns-servers server-1 8.8.8.8
set vpn l2tp remote-access dns-servers server-2 8.8.4.4
set vpn l2tp remote-access ipsec-settings authentication mode pre-shared-secret
set vpn l2tp remote-access ipsec-settings authentication pre-shared-secret NOTGONNATELLYOU
set vpn l2tp remote-access ipsec-settings ike-lifetime 3600
set vpn l2tp remote-access mtu 1492

So with regards to this bit The part that is going over with Unencrypted PAP is testuser/Testing!123. I wonder if requiring encryption is actually encrypting the username and password.

But how, how does it work?

The username/password being encrypted depends on the authentication method. If using PAP, they are sent in clear text, for example.

That is my point of contention, cisco recommends "requiring encryption" when using PAP, yet it doesn't matter.

So why bother with a recommendation that clearly doesn't work? Is it just to provide the warm and fuzzies?

Reasonably likely.

Reasonably likely.

Is that in any way reasonable to you as a professional?

No, but neither is choosing Cisco

That's mostly tongue in cheek, but only mostly.

Cisco wasn't his choice, nor Meraki...

I gotta get back to my desktop and read closer. I did see your point though originally. And is it only recommends to use PAP?

Yeah he's got that. When you click on his link search the page for PAP and read the boxes comment. That's what we are mulling over.

Didn't say it was. But his question was was it good for Cisco to make that decision, but the real question is... why did someone choose Cisco if it didn't meet the needs?

The whole setup likely won't matter soon, the issue came up because I had to setup a large number of systems with VPN, and I didn't want to have to go and by hand configure every system.

So i wrote a powershell script to do it, based on the information I had in our documentation and that is where I found the weirdness with this "require encryption".

PS 4 flat out said "nope go pound sand, that isn't a valid option". I can manually make this change, yet I want to understand why I should bother?

I can connect with "minimal" or "require encryption" in either case. Does "require encryption" do something? (not that I can see).

The real question is, why the hell is this the "configuration method" that is recommended by Cisco.

Not "why did someone choose cisco if it doesn't meed the needs".

That is a derailment from the question I have, which is "wtf is this doing, if it is clearly wrong?!"

I'm sure there's some context ties to an old support ticket where someone said something meraki recommended wasn't secure and then some engineer updated the article, etc

Crazy people with emotional reactions to the name IoT when no IoT exists, and people fearing Windows 10 compared to 7. WTF people?

What does IoT even mean in this case? I've always been unclear on it..

IoT is the name of the OS version. There is no IoT involved in his use case.

IoT is not a real term, it doesn't mean anything specific. It's a loose reference to devices that you'd not expect to be computing devices that are networked, but are. POS doesn't fall into that category. Your toaster, microwave, or fridge would. A sensor in your attic might. Thermostats really can't be considered this any longer, they are full computing devices and expected to be so, now. So they've left IoT, IMHO.

IoT is a useless term based around the cluelessness or expectations of the observer. It is always subjective and can't be used in any technical context.
