Well, it just works for me, but this is on the latest Sky Dlink. No setup required.


Too many types of VPN - for example:

1) PPTP
2) Native IPsec
3) IPsec encapsulated in UDP
4) SSL

The first two generally need the router to assist, in many cases "VPN passthru" or similar options need to be enabled. My clients use 2 only, which is the hardest to get working. Older Cisco VPN uses 2 only, but newer and "AnyConnect" can use 4.

Both 1) and 2) work for me. I haven't tried OpenVPN or 4).
But we are talking about the client being behind the Sky router, not the server.

Does OpenVPN do 3 then? I know Cisco Anyconnect does 4.

Correct, a VPN server needs to be on a real static routed IP smile Hosting a VPN server (or concentrator in cisco speak) behind a NAT is a labour of love wink

I have a VPN server behind a NAT on a dynamic IP, but I suspect you mean something else.

I doubt they do.

VPN servers behind NAT while feasible can be difficult to setup, hence the preference by many for a VPN server hosted in the router itself.

Now I do expect you to have a suitably obtuse response, that reveals nothing of the technical way in which you operate this VPN behind NAT.

That's a good point, I'll bet the router manages to host a VPN server on a dynamic IP.

PPTP is doable (heck it was half designed by Microsoft who think about end/home users)

Original IPsec is a big problem; I'm told, but then there were modifications to the IPsec protocol design, but the problem is not all vendors implemented these optional parts. Original IPsec was intended for data centre to data centre (fw to fw) type links.
