OpenVPN update breaks R7000 and probably other routers VPN implementation
OK Just updated my R7000 router to firmware 188.8.131.52 and finally got VPN working again under the windows client - more on that later.
However, I am now trying to get it working on a remote router with DD-WRT loaded. This was working under 184.108.40.206 firmware with the old certificates.
I have downloaded and put the new certificates onto the DD-WRT router OPENVPN CLIENT page but I can’t get a connection.
I notice the update log for v 220.127.116.11 says:
* Added support for SHA256 certificates in lieu of MD5 for OpenVPN
Would any one happen to know if this means I need to change the hash algorithm box to SHA256 ? (It was previously SHA1)
And are there any other changes I need to make?
Now back to that comment about getting the windows client to work. I am not sure which of the following steps fixed it but I did all of these:
(I'm on Windows 10 - updated this morning to whatever todays latest version is)
0) Upgraded R7000 firmware to 18.104.22.168
1) Uninstalled the old Windows client V2.4.x - can't remember which one)
2) Made sure the TAP adaptor had been deleted on the network adaptors page.
3) Manually checked ALL the places the client1.ovpn files could be stored - there’s several now it seems.
4) Made sure there were no files or directories left in the C:\PROGRAM FILES\OPENVPN directory.
5) Downloaded new certificates from router
6) Downloaded latest version of Windows OPENVPN client (v2.4.6)
7) Installed client
8) Remembered to rename TAP adapter to NETGEAR-VPN (eventually.)
9) Copied (manually) certificates and client1.ovpn to C:\PROGRAM FILES\OPENVPN\CONFIG
10) Started client - this version no longer needs to run as an administrator like previous versions did - if the user is an admin already
11) Connected normally.
12) Had a congratulatory cup of tea.....
13) Posted this here in case its any use to anyone else.
