Can't establish VPN tunnel between PFSense & Sonicwall (06.08.17 it works!)

pfrickroll

Anyone at all?

Perhaps something to do with your username…
Here are a few observations, recommendations-

Don't use 3DES, the Sonic will support AES
Use main mode on the pfSense side, not aggressive
Don't put the public IP in the ping host on the phase2. This should be a private IP reachable via the tunnel.
You should be able to leave the identifiers at 'my ip address' and 'peer ip address'
Two Comcast lines? They are not at the same location are they?
6) If the tunnel is disabled, it will never work. Find out why this is happening first. Start your config from scratch if necessary.

Thank you for your reply. I doubt my name scares people away :)
I changed everything you mentioned in 1-4.
The two lines are Comcast and they are not in the same location. Two separate offices in different cities.
I rebuilt the config from scratch and still nothing. Here you can see, when I click edit phase 1 the check mark is always on "Set this option to disable this phase1 without removing it from the list". The both phases are enabled but only phase 1 has this check mark on. I try to unmark it, save and apply change, then I go back to edit and that mark is checked again.
And of course I changed config settings on SonicWALL to match pfSense.

Maybe not scared away…

Something is up with your phase1 settings- It doesn't start disabled, and I've never seen it disable itself.
Post all of your phase1 settings, there must be something it doesn't like. Are you getting any IPSec errors in the log when you try to enable it?

Here are my phase 1 settings and IPsec Logs. I first cleared the logs and then disabled IPsec. Then I clicked to edit it, unmarked that disable feature in phase 1, then enabled Ipsec log and this is what info came up in log for IPsec. Now, I even myself noticed both firewalls talked to each other but something went wrong and it beyond my experience, I just began learning of encryption.

Still pretty tough to tell looking at only one side.

You should probably post a new set of screen shots from both sides showing the current state of things as a pair.

The sonicwall doesn't like something and is returning "INVALID_SYNTAX" in the Phase 1 negotiation. Concentrate on Phase 1/IKE for now since you are not even getting to phase 2. The reason the sonicwall is returning that might be in the sonicwall logs.

Set the following to Diag in VPN > IPsec, Advanced, Logging: IKE SA, IKE CHILD SA, and Configuration Backend. Set everything else to Control.

dotdash

Yeah, most of the stuff in the logs is normal until you get to the last shot.
Try setting Key Exchange to V1 instead of Auto.
The syntax error is unusual, I think this is what is disabling the phase1. Try deleting the phase2 and unchecking the disabled box on the phase1. Then verify the service remains running. If that's good, add the phase2 back in.

I dont see such option here, everything is set to control by default, as you see in the picture
2nd pictures is Sonicwall logs for that particular time.

Ah sorry, my bad English kicked in. Going to change now to Diag those configs.

Those sonicwall logs don't really say much. I assume they are descending later to earlier in time?

@Derelict:

No, that is the only info in logs for VPN between these pfSense and Sonicwall. Nothing before or after.

dotdash

Looks like pfSense proposed a v2 exchange and the Sonic was set for v1.
Change the auto setting to v1 and try again.

pfrickroll

I set those configs to Diag. Here are the logs for IPsec and Sonicwall

You know you can copy and paste text instead of screen shots of those logs right?

OK so you're now getting through phase 1. The INVAL_ID error means the networks on your side do not match what the other side has configured.

You have:

Local: 192.168.0.0/16
Remote: 192.168.3.0/24

That /16 is almost certainly wrong and probably will not work.

pfrickroll

Ok, so rebuilt pfSense tunnel from scratch again with IKEv1 version and 192.168.10.0/24 subnet

This is pfSense IPsec config, I don't know is there an option to copy/paste short log config of IPsec, so I just screen caped it.

The errors point to a settings mismatch. Verify the phase 1 and phase 2 setting match exactly. (Of course the remote gateways and local/remote networks would be switched.)

I will check later tonight again, don't have time at the moment.
But i just want to say thank you very much for reading and responding to my post.
