      I am having this problem with connecting to multiplied pfsense based openvpn server at the same time with openvpn client for Windows 10.

      I have 7 taps installed and it works fine on centos based openvpn server but with pfsense I just get the error: Connecting to VPN has failed.

      Logfile from OpenVPN client:
      Wed Jan 29 14:39:07 2020 OpenVPN 2.4.8 x86_64-w64-mingw32 [SSL (OpenSSL)] [LZO] [LZ4] [PKCS11] [AEAD] built on Oct 31 2019
      Wed Jan 29 14:39:07 2020 Windows version 6.2 (Windows 8 or greater) 64bit
      Wed Jan 29 14:39:07 2020 library versions: OpenSSL 1.1.0l 10 Sep 2019, LZO 2.10
      Enter Management Password:
      Wed Jan 29 14:39:09 2020 TCP/UDP: Preserving recently used remote address: [AF_INET]xxx.xxx.xxx.xxx:1194
      Wed Jan 29 14:39:09 2020 TCP/UDP: Socket bind failed on local address [AF_INET6][undef]:1194
      Wed Jan 29 14:39:09 2020 Exiting due to fatal error

      Even changed port for openvpn while testing so it looks like this:
      PFsense VPN server 1 is running on port 1194
      PFsense VPN server 2 is running on port 1195

      Anyone have an idea how to fix this because it's nessary to be connected to both servers at once because VPN server 2 are only allowed to communicate on ports 1194-1196 and others cannot be opened and ipsec doesn't work if it did I would set up IPSec from server 1 to server 2 and use one vpn to server 1 or 2 and my problem would be solved.

        Do you have an lport line in the clients configs? If not try to add the line

        lport 0

        to it.

          @viragomann I do not have lport 0 in the client config anywhere specific in the config where it needs to be inserted?

            lport is the local port, the OpenVPN client instance binds to. It should default any if it's not stated, but maybe that doesn't work in your set up.

            lport 0

            sets the port to any, which means OpenVPN should select the next free port. So you may give it a try.

              I haven't seen this as default in any config for openvpn that I work with but it connects and I can ping so far it's working thank you @viragomann
