Vendor changes notwithstanding, all versions of openvpn from 2.2.x to 2.4.x should interoperate nicely. In some cases, issues arise due to newer SSL libraries - like, if the E4200 generates a MD5 signature for its certificate, newer clients will not accept this without config changes (because SSL libraries consider MD5 grossly insecure nowadays). But in general, you should be fine. gert -- "If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out.

My router openVPN is v2.4.3. I guess I can use the latest client on my computer to work with it.

Generally install the latest version, although on Linux you can probably stick to whichever version your package manager provides. Different versions shouldn't be an issue, but you could run into crypto library (OpenSSL) compatibility issues if the age gap is several years. To find the OpenVPN version on your router, open the command line and run "openvpn --version". Some other commands you may want to run on both client and router are "openvpn --show-tls" and "openvpn --show-ciphers" to check that they have some compatible choices between them. While I always recommend running up to date software, tread carefully if upgrading your router firmware. Read documentation and read it again, because things will go wrong if you use the wrong file, do things in the wrong order, the magic numbers are off by one or the wireless antennas are not aligned with the horns of the unicorn standing on the north pole of Mars. > thanks, > > James /Magnus -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users

[Openvpn-users] dd-wrt router openVPN server version and client version must be the same?
Hello everybody, I have bought an used Linksys E4200 version 1 router and was told the openVPN was installed already. Now I am trying to set it up. I need to install a client on my computer and generate those files. which client version should I install on my computer? The same version as the dd-wrt router or the latest version? if the same version as the server is required, how can I find the openVPN server version? thanks, James -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot___ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users
