I attempted to replace my current OpenVPN RSA certificates with EC cryptography because of its greater strength at much smaller key sizes. However, I run into some connectivity issues, which I am certain are unrelated to configuration as it works just fine for RSA certificates.

The openvpn config and log file from one of your clients (behind the dodgy router) might be of some assistance at --verb 4 If: (1) your router is simply being a router/modem and not doing any encryption/decryption (2) and all the clients behind only that router have the same problem when using openvpn We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will remain NSIS-only. Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless Client = OpenVPN GUI 11.14.0.0/2.4.8 (config and installer generated by pfSense client export plugin) Server = OpenVPN on up-to-date pfSense OS = Windows 10 Pro, feature pack 1803 Laptop = Lenovo ThinkPad E550 User is a domain user with Install and Configure OpenVPN Client on CentOS 8/Ubuntu 18.04.

Command examples: verb 4 -- change the verb parameter to 4 mute -- show the current verb setting COMMAND -- version ----- Show the current OpenVPN and Management Interface versions.

The problem is I am getting disconnected from my OpenVPN server exactly after 1 hour and I can't understand what directive/option is reponsible for this.

However, I run into some connectivity issues, which I am certain are unrelated to configuration as it works just fine for RSA certificates.
