Hi Jean-Philippe
That solution appears to be nice. It would be acceptable.
I've looking at
https://wiki.contribs.org/OpenVPN but it:
1) appears be done to SME7 and 8 , not SME9
2) is hard to follow with a lot of details.
DOUBT: I'm not sure WHERE is the blocking feature that allow access just to server (not other things on network). I've seen /24 masks (255.255.255.0) not /8 masks!
I'm using PPTP on this server (just for me and small company owner).
Do you think it's safe to try to enable OpenVPN on server ?
I've a PFSense on that network (and it supports OpenVPN): by change , do you know if could I use pfSense for this ?
