OpenVPN freeware - The Latest User Reviews
OpenVPN freeware - The Latest Versions History
2.5.0 Oct 28, 2020 New Release Faster connections:
Connections setup is now much faster
Crypto specific changes:
ChaCha20-Poly1305 cipher in the OpenVPN data channel (Requires OpenSSL 1.1.0 or newer)
Improved TLS 1.3 support when using OpenSSL 1.1.1 or newer
Client-specific tls-crypt keys (–tls-crypt-v2)
Improved Data channel cipher negotiation
Removal of BF-CBC support in default configuration (see below for possible incompatibilities)
Server-side improvements:
HMAC based auth-token support for seamless reconnects to standalone servers or a group of servers.
Asynchronous (deferred) authentication support for auth-pam plugin
Asynchronous (deferred) support for client-connect scripts and plugins
Network-related changes:
Support IPv4 configs with /31 netmasks now
802.1q VLAN support on TAP servers
IPv6-only tunnels
New option –block-ipv6 to reject all IPv6 packets (ICMPv6)
Windows-specific features:
Wintun driver support, a faster alternative to tap-windows6
Setting tun/tap interface MTU
Setting DHCP search domain
2.4.9 Apr 17, 2020 New Release New features:
Allow unicode search string in --cryptoapicert option (Windows)
User visible changes:
Skip expired certificates in Windows certificate store (Windows) (trac #966)
OpenSSL: Fix --crl-verify not loading multiple CRLs in one file (trac #623)
When using "--auth-user-pass file" with just a username and no password in the file, OpenVPN now queries the management interface (if active) for the credentials. Previously it would query the console for the password, and fail if no console available (normal case on Windows) (trac #757)
Swap the order of checks for validating interactive service user (Windows: check config location before querying domain controller for group membership, which can be slow)
Bug fixes:
fix condition where a client's session could "float" to a new IP address that is not authorized ("fix illegal client float")
This can be used to disrupt service to a freshly connected client (no session keys negotiated yet). It can not be used to inject or steal VPN traffic.
