Download OpenVPN 2.5.4

OpenVPN is a robust and easy to set up open source VPN daemon that allows several private networks to be linked together through an encrypted tunnel over the internet. For security, the OpenSSL library is used, which can handle all encryption, authentication and certification. The developers have released version 2.5.4 and the main changes in it are listed below for you.

Bug fixes

• Fix prompting for password on windows console if stderr redirection is in use – this breaks 2.5.x on Win11/ARM, and might also break on Win11/adm64 when released.
• Fix setting MAC address on TAP adapters (–lladdr) to use sitnl (was overlooked, and still used “ifconfig” calls)
• Various improvements for man page building (rst2man/rst2html etc)
• Minor bugfix with IN6_IS_ADDR_UNSPECIFIED() use (breaks build on at least one platform strictly checking this)
• Fix minor memory leak under certain conditions in add_route() and add_route_ipv6()
