Hi Folks,
I'm using OPNsense 18.1.r_15-amd64. and I'm trying to get IPsec Road Warrior VPN configured.
I'm following the steps here:
https://docs.opnsense.org/manual/how-tos/ipsec-road.html
And on Step 4 (Add IPsec Users) it says:
"Add privilege User - VPN - IPsec xauth Dialin by pressing the + under Effective Privileges."
I don't see a "+" under Effective Privileges. Under Effective Privileges the only button is an edit button (pencil)--If I press this, then I get a list of GUI components, and none of them say "IPsec xauth Dialin". In fact none of the options have xauth in the title. I have these selected: - GUI VPN: IPsec and
- GUI VPN: IPsec: Mobile
Am I doing something wrong, or have the options changed since the documentation was created?
When I configure the native client in OS X, I get this error when I try to connect: "The VPN server did not respond. Verify the server address and try reconnecting."
Would someone please point me to some updated docs or steps to try to diagnose this issue?
Also, just checking, should the IPsec VPN be working with OPNsense 18.1.r_15
I've applied the patch: opnsense-patch 0ec330d7
per this thread: https://forum.opnsense.org/index.php?topic=6843.0
I would greatly appreciate any tips or pointers.
Thanks!

Hi Ooker,
I'm having similar issues following the same steps but I'm on 17.7.11.
For the first issue, for me the search feature at the top of the System Privileges screen returns the correct priv if you search on Xauth. If it doesn't show up I can only assume there is something different in 18.1.
Regarding OSX connectivity issue, this is the issue I have. You need to check the "VPN -> IPSec -> Log file" and see what it is reporting as an issue. For me it appears that I can connect, but the connection is immediately dropped.

Hi Dobbin,
Thanks for your reply.
Here's what I did, and what I see:
On 18.1r1 If I go to System->Access->Users
Click on the edit/pencil for the user in question
Then Click on edit/pencil in Effective Privileges
There is a Search Field under description, and if I type in Xauth I get no results.
In fact, my list only contains results prefixed with "GUI"
Are you seeing other prefixes?
Based on the description in the docs of "User - VPN - IPsec xauth Dialin" I got the impression that it might have a different prefix other than "GUI"
Examples of what I see:
...
GUI Status: IPsec
GUI Status: IPsec: Leasespage
GUI Status: IPsec: SAD
GUI Status: IPsec: SPD
...
Are you getting options where the first 3 letters are different from GUI? What is the option that comes back when you search for Xauth?
-
Well, this in the 181.r1 release notes...
https://github.com/opnsense/changelog/blob/3caefd257e834042c364741e6ccb8927c89f568c/doc/18.1/18.1.r1#L77
The Xauth privilege is no longer needed. If you want, you can restrict local authentication to a local group of users. It follows a change done early in 17.7.x which followed a change done in the captive portal some time before that.
Since 18.1 is not officially out the docs still refer to version 17.7 and will be fixed accordingly when it's time.
Cheers,
Franco

Hmmm. I must have something wrong with my firewall config. I'm not seeing anything in the IPsec log when I try to connect from my Mac Client. I have verified that the WAN address is correct. My Mac Client is accessing the net via a Verizon Jetpack MiFi box.
I've verified that Block Private Networks on the WAN interface is disabled, and the two screenshots show my WAN and IPSEC firewall rules.
Can anyone suggest steps to try to diagnose this further?
For example, should telnet be able to connect to port 500 or port 4500 on my external WAN IP? Does anyone have a good IPsec VPN troubleshooting guide to recommend?
-
I have re configured the server and the client and I am at least getting an IPsec VPN Log. Does anyone have suggestions regarding what may be going on, and/or next steps to diagnose this issue further?
The Mac VPN client now fails with "The negotiation with the VPN server failed. Verify the server address and try reconnecting"
Here is the log data:

In The VPN->IPsec->Status Overview, my status icon at the right of the display is orange. Should it be green? I couldn't find any info on this in the documentation.

I'm having the same problem with OPNsense 18.7.3-amd64. I followed the instructions per the documentation and my macOS client still can't connect. I also have an orange status icon. I tried to change the detail in my logs with no success even after reboot. The detail I do get is useless. Apparently I can establish Phase1, but don't have a clear picture of what is happening in Phase2. Not being able to get better detail in the logs is most upsetting. A close second is following instructions that are outdated. Here my log output:
