@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.

Believe it or not, someone on this thread from yesterday

[EddieJennings]

Today's gem:

User: Paper shredder in [another user]'s office has died after 10 years. I can find the identical one [from a vendor] but [it's used, and I'm not comfortable buying used]. Any thoughts on where to find the same one?

Me: The odds of you finding an identical replacement for a 10 year old device are slim to none. Better approach would be determine desired features, set a price point, and go shopping.

User: Let me see what I can come up with.

User: Let me see what I can come up with.

User: Desired features = at least 10 years old, looks and works just like the old one.

You : ..............

User : what are "specifications"???

[EddieJennings]

Umm.

I keep getting answers to questions I ask in Slack while I type stuff in Spiceworks, causing me to be beind you :P.

Slacker

I love how often threads are so insanely straightforward, and then the person answers something that doesn't match anything anywhere on the thread. It's like they can't read or are having a stroke or something.

Network drive loaded onto a Cisco router. Um... https://community.spiceworks.com/topic/2084210-need-help-with-network-storage-encryption

This guy doesn't seem to know what a NAS is, a router, BitLocker or encryption.

So he encrypted a drive and is surprised that it is encrypted?

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 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 without the "Require encryption" the preshared key is sent in plain text?

I do not know enough about the protocols to definitively answer that, but the entire IPSEC protocol does not use the PSK until phase 2. Phase 2 is encrypted with the exchanges sent in phase 1.

The preshared key used in your example and mine is an IPSEC bit, not an L2TP bit.

So then it shouldn't matter, "Require encryption" or Optional or Minimal should do nothing to add / improve the encryption since IPSEC is doing all of it.

Does anyone know the protocols well enough to explain this? Why is "Require encryption" recommended, when it doesn't follow/appear to follow the standard and actively reports an error if you attempt set this up via powershell.

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

And as expected nothing there for PAP is offering "Require encryption". I wonder if it's just weirdness or if there is some bug that without "encryption" information is passed in plain text. . . (some how. . . )

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.
