Spark 1550 VPN not working behind simple Unifi network

inogueira — Tue, 09 May 2023 19:06:02 GMT

Hi!

I'm using a Quantum Spark as VPN gateway connected to our office server. If I use it through a consumer 4g router it works, i can see office local ip's.

If I use it connecting wan port to a Unifi network (Unifi Dream Machine) with IPS, IDS and threat management off the VPN doesn't work. I can open web pages through it, but I can't see center office local IP's.

Is there anything I can do?

Thanks!

Which firmware version is the gateway deployed with?

Does basic traffic like ping work or no?

Can you see in Unifi logs if VPN packets get dropped ? Can you configure a Bridge mode ? I would rather ask Unifi support for help in this case...

How can I do this?

Have you tried doing basic vpn debugs to see what they show?

I agree with @G_W_Albrechtand would check the dream machines configuration. To get the VPN up the dream machine has to allow UDP/4500 (IPSEC NAT traversal) and VPN must be initialised from a host behind your spark appliance.

So, I have to open port 4500 UDP to my ckeckpoint IP?

It should be open, yes.

I would suggest to contact CP TAC if the problem is still not resolved !
