We have a test server running that has Elastix 2.4 with OpenVPN installed. I have confirmed that I can connect from a Windows PC running an OpenVPN client, but when I try to connect a T38, it fails.

Prepend a one-byte OpenVPN data channel P_DATA_V1 opcode to the packet. More void tls_prepend_opcode_v2 (const struct tls_multi *multi, struct buffer *buf) Prepend an OpenVPN data channel P_DATA_V2 header to the packet. More void tls_post_encrypt (struct tls_multi *multi, struct buffer *buf) Perform some accounting for the key state used

6. OpenVPN 6.1 Introduction SSLVPN is common name for a VPN implementation based on the SSL/TLS protocol suite. An SSLVPN is implemented as a module executing in the ease-to-use user-space context instead of the kernel ring of the operating system. Just for the sake of completeness, this was neither a networking/firewall issue nor OpenVPN configuration. Just some of the clients (connected via prepaid 3G) did not have enough balance The twist is that the outgoing packets from the client could reach the server, but the incoming packets from the server could not reach the client. I also tried this with viscosity. pfsense logs: 144.121.5.10:1194 Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #1 / time = (1534446687) Thu Aug 16 15:11:27 2018 ] -- see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings Aug 16 15:11:27 openvpn 83547 144.121.5.10:1194 TLS Error: incoming packet

I can't make an OpenVPN server work with the new easy-rsa 3.0 setup. Worked flawlessly in the past with the bundled 2.0-branch. Tried it on two separate host providers (one with a working legacy config). # uname -a Linux server-asia 3.13

Hello, I am running OpenVPN on OpenWRT and there seems to be some problem after the latest PolarSSL version (1.3.10): Thu Mar 5 08:43:54 2015 OpenVPN 2.3.6 mips-openwrt-linux-gnu [SSL (PolarSSL)] [LZO] [EPOLL] [MH] [IPv6] built on Mar 4 2015 Thu Mar 5 08:43:54 2015 library versions: PolarSSL 1.3.10, LZO 2.08 Thu Mar 5 08:43:54 2015 WARNING: file '/etc/openvpn/pass.txt' is group or others Thinking perhaps something was broken in an RC snap I downgraded to a Beta5 snap from Thu Jan 27 07:01:20 EST 2011 when I know the OpenVPN config worked (restoring a config from back then as well right now to test with). The firmware downgrade didn't help at all. So, I'm obviously doing something very wrong in my setup. Added new packet format P_DATA_V2, which includes peer-id. If server supports, client sends all data packets in the new format. When data packet arrives, server identifies peer by peer-id.
