Has anyone got a VPN to a Draytek working?

[stephenw10]

I have seen that a number of times. Draytek have a lot of devices and firmware versions of course.

More detail required. How are you configuring it? What's happening / not happening?

Check the logs for errors.

Does this make any sense to anyone? I've got a site-to-site to a Watchguard working, but not this one. Thanks in anticipation!

That looks like a shared key mismatch is most likely.

Anyone know how to fix this please?

[orangehand]

Apologies Stephenw10 - I hadn't clocked that you were in-house pfsense! Am very grateful for your assistance!

[orangehand]

(The only change today is that we changed the connection to IKEv2 and DH gp2)

[orangehand]

(and Draytek is set to Dial Out, always on)

[stephenw10]

I assume the Draytek logs are in reverse order again?

Did you change to IKEv2 and DH group2 at both ends? pfSense will use IKEv2 if it is initiating and it's set to auto.

The pfSense failure log will probably be more useful here, obviously we are far more familiar with it.

However I would say it's most likely an identifier mismatch looking at those logs. IKEv2 has a much larger choice of identifier types. It looks like the Draytek has accepted whatever pfSense is sending as it's showing SA established but pfSene then sends an authentication failure message.

Since you're using public IPs at both ends if the identifiers are still set to 'my IP' and 'peer IP' that should work.

Steve

[orangehand]

Yes both ends were changed, whilst I had the Draytek guy remoted into my Mac
(The Draytek is set to dial out, not both, if that matters)

[orangehand]

Here is the draytek end - there appears to be no peerID setting that end if that might be relevant?

[orangehand]

The top and bottom of the previous screenshot:

[stephenw10]

Ok so not an identifier mismatch, thay are sending their IP as identifier shown in [ ]

looking for peer configs matching 81.143.205.132[%any]...88.97.12.47[88.97.12.47]

It still looks like the preshared key is wrong:

tried 1 shared key for '%any' - '88.97.12.47', but MAC mismatched

I would test it by using a super simple key that cannot me typo'd or translated like 12345. Move to a better key once it connects with that.

We can't see the actual encryption settings there, I assume they are under that advanced button. If the HMAC didn't match there I would expect it to fail with a proposal error. It was matching previously for IKEv1 but worth checking.

Steve

[stephenw10]

Are you using an especially long PreSharedKey? The maximum ley length is related to auth hash used and you are using SHA1 which limits it to 64B (I think).

Steve

[orangehand]

Changed PSK to 12345, saved and applied at both ends

Sorry - missed your key length Q; no - previous psk was testtest - the last logs were 12345

[stephenw10]

Hmm, curious.

Is this the only tunnel at each end?

Does either end have more than one WAN?

Can we see the config at the pfSense end?

@orangehand said in Has anyone got a VPN to a Draytek working?:

looking for peer configs matching 81.143.205.132[%any]...88.97.12.47[88.97.12.47]

Ok in fact this could be an identifier issue. It looks like the Draytek is sending 'any' as the identifier for pfSense. What is it actually set to in pfSense?

I don't see a place to specify a peer ID in the Draytek settings other than the 'dial-in' section but you might try adding it there.

[orangehand]

In dial in settings you mean the username field? What would I put there please?
