New Full Fibre 1.6Gbps - Slow VPN Connections

[Fogzter]

Hi

I've just had my 1.6Gbps full fibre installed yesterday and without my VPN switched on I'm receiving the full 1.6 down and 115 up.  However when connecting  my Surfshark or Mullvad VPN using Wireguard protocal the speed drops to around 500Mbps.  I've tried deleting all my VPN connection on my Unifi router and recreating my key pairs etc as well I setting up different VPN servers but the speed is always the same.  I've also tried setting up OpenVPN, both TCP and UDP and these are even worse with speeds around 200Mpbs.

So my question is do EE perform some sort of throttling on VPN connections and is there a way around it?  If not then I'll need to cancel my contract as I'm still in my cooling off period and wondered if anyone has recomendations on whose services works best with VPN conntions?

Thanks

@Fogzter That makes a difference then now, looking like Unifi need to FW check the VPN server/client on there gateway. Does not take much to mess up a connection at all.

Thanks @JimM11 I've got a support ticket logged with them, so will let you know what they say.  Cheers

@Fogzter Pictures are all cleared now, VPN Off/On is as about expected with the latency and your Use 1500 MTU is off WAN settings which is helpful but would need to dig into unifi info if correct settings. No two routers are alike, what is good for one may be bad for the other.
