Which may not be possible. A quick read of https://nodogsplashdocs.readthedocs.io/en/stable/howitworks.html suggests it's only concerned with controlling the incoming local interface, i.e. the Pi's Wi-Fi, so I'm surprised it hampers a VPN. Perhaps it's the VPN which thinks it too has to look after the Wi-Fi interface and causes the interference. Careful study of the iptables(8) at various stages may show what changes occur. > > The bottom line: Can macvlan interfaces be used in this instance? ... > Would this be the way to go? Sorry, I've no idea. On your duplicate test rig, I'd disable nodogsplash and get other things working, e.g. a reverse-forwarding SSH client and WireGuard. (I think I noticed PiVPN supports WireGuard.) Then, with two sets of working configurations, I'd try and get both going at once, being sure to limit the bits of the network each treats as theirs. If there's a conflict then that might be the time to complicate things further by adding virtual network devices, having understood the nature of the conflict. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2020-07-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
