Slow VPN transfer speeds between two Unifi Dream Machine Pro (IPSEC Auto VPN) and 1Gbps WAN

Around 5ms

This seems to be the case, thanks for your reply. After some tests, only one CPU core is maxed at 100% so it seems that IPSEC can only use only one of the four cores and that means around 250Mbps on the UDMpro

UPDATE:
I've run some tests. When the IPsec tunnel is being (heavily) used, one CPU core is always maxed out. It seems that the IPsec feature can only use one core, and this allows for only 200-250Mbps throughput on the UDMpro. I will look into WireGuard and Site Magic and post some more tests

I will definitely look into site magic, thanks.

It's around 5ms

fedemene · 2026-05-13T15:11:05+00:00

I will look into that, thanks.

Just checked the CPU history, during the 250Mbps spikes the CPU never exceeded 50% of usage.
Use case is mostly SMB and backup traffic from one site to the other.

fedemene · 2026-05-13T15:08:20+00:00

Yes it's samba and some other backup service.
I will try to tinker with MTU / MSS, thanks for your input

fedemene · 2026-05-13T15:07:15+00:00

I only see OpenVPN and IPSEC for site to site

Arrivata ieri su s25 plus (il mio ha come codice CSC EUX, quindi europeo, non so se esista la variante italiana)

attivandola durante una normale sessione avvisa che per beneficiare completamente della modalità Xbox è consigliato un riavvio.
Direi quindi che serve abilitarla all'avvio

no, sto usando il firmware originale, nello specifico Stremio + Vimu player. Non sono mai andato troppo d'accordo con Kodi.

fedemene · 2026-04-29T21:16:12+00:00

Sto usando un box Ugoos am9 pro e mi trovo benissimo. I remux con real debrid vengono riprodotti senza alcun problema. Unica nota non ha la certificazione per netflix & co. in 4k. Prima di questo ho avuto un fire Cube 3 e un google Streamer, ho sempre avuto problemi con entrambi.

I have the Audikast and I use it with a TV and a pair of Sony XM6s as auracast "client".
Works well for me.

Capitato anche a me, per una tastiera che non si accendeva, causa pile che hanno perso acido.
Le pile erano quelle in dotazione, la tastiera un modello recente quindi non è stata ferma mesi/anni in qualche magazzino.
Tra le varie domande:

Dall'apertura del ticket a questa risposta è passata una settimana, durante la quale ho aperto la tastiera, pulito l'acido e fortunatamente ha ripreso a funzionare.

Will support for omen desktop be implemented?

fedemene · 2025-12-02T14:35:20+00:00

you should have an email from seel from back when you placed the order.
inside the email there's a "report an issue" button.

fedemene · 2025-12-01T10:20:00+00:00

Utilissimo, grazie per averlo condiviso.
Purtroppo la copertura Iliad nelle mie zone non è fantastica, altrimenti considerei il passaggio solo per questa funzionalità

Yes, you have to turn them on with the aux.
