Frequently Asked Questions

Can I run OPNsense 24.x Kernel WireGuard & Multi-WAN Gateway alongside the SWEEPR VPN desktop app?

Yes. Every SWEEPR VPN plan supports up to 10 simultaneous WireGuard peers across routers, NAS appliances, Linux servers, Windows, macOS, iOS, and Android.

What DNS server should I use on OPNsense 24.x Kernel WireGuard & Multi-WAN Gateway?

Always set your WireGuard interface DNS to 10.66.0.1 so DNS queries travel inside the encrypted WireGuard tunnel and cannot be intercepted by your ISP.

Why are my HTTPS pages stalling after enabling WireGuard on OPNsense 24.x Kernel WireGuard & Multi-WAN Gateway?

If your ISP uses PPPoE (such as BT, Sky, TalkTalk, Plusnet, or Vodafone FTTP), lower the WireGuard interface MTU from 1420 to 1412 and enable TCP MSS clamping to 1352–1360.
