It uses the OpenSSL library to support strong encryption protocols like AES-256 and ChaCha20 and establishes secure connections using TLS.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>OpenVPN is popular because of its flexibility. <strong>It can run over either UDP or TCP, and on virtually any port.<\/strong> This includes TCP port 443, which allows it to disguise itself as regular HTTPS traffic, making it compatible with restricted networks.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>While it\u2019s not built into most operating systems, OpenVPN software clients are supported on almost any device, including routers, desktops, and mobile devices.

Whether you\u2019re downloading large files, <a href=\"https:\/\/www.privateinternetaccess.com\/stream-sports\">watching live sports<\/a>, or playing fast-paced online games, IKEv2 delivers faster throughput and steadier performance on stable networks.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>OpenVPN, meanwhile, offers better resilience in tricky environments. If your ISP or local network throttles UDP traffic, OpenVPN can switch to TCP mode and run through port 443, the same port used by HTTPS traffic, to keep your connection alive.
