      Hello,

      I have a OpenVPN server, under pfSense 2.1.5 x64.

      My OpenVPN Settings is posted in picture attached.
      Certificates usses a SHA256 Digest Altgoritm (both Server and User Certificate).

      The problem is this:

      • I can succesfully access and connect to OpenVPN server from almost anywhere, but from work just don't want to work.

      I think is some restrictions on our Enterprise Network, because server work from anywhere else I tested, but not from work.

      My question is if you know some port/encryption/certification etc… settings that should work from anywhere, like nobody can block this connection to OpenVPN.

      Thank you verry mouch!

        perhaps they are using a proxy of some sort at work?  Proxy breaks vpn usually.

        (proxy wouldn't impact udp much probably - I just saw that.  But UDP on 443 might be blocked in the office)

          You may try it with TCP protocol.

            We use a Proxy at work, but I tried to connect on TCP/443 with no succes
            My config file looks like this:

            dev tun
            persist-tun
            persist-key
            cipher AES-256-CBC
            auth SHA1
            tls-client
            client
            resolv-retry infinite
            remote server.go.ro 8080 tcp-client
            lport 0
            verify-x509-name "pfSenseOpenVPN" name
            http-proxy XX.XX.XX.XX 8080  proxy-credentials.txt ntlm
            auth-user-pass
            pkcs12 server-TCP-443-SSL_VPN.p12
            tls-auth server-TCP-443-SSL_VPN-tls.key 1
            ns-cert-type server
            comp-lzo

            And I created a proxy-credentials.txt where on first line I put username, and on seccond line I put my proxy password, and still don't work.

            It give me this error:

            Tue Feb 10 16:56:10 2015 SIGTERM[soft,init_instance] received, process exiting

            If you have any thoughts on this it will be really usefull.

            Thanks.

              I connect to pfsense openvpn using tcp 443 over a proxy from work every single day.  In your openvpn gui, just setup your proxy..

              is it http or socks?  Do you have to auth to it?

                It is HTTP, and use auth.

                  Well good luck with that…  You can not send auth from the gui setup.  Maybe you can do it in the config?

                    OK. I finaly made this work.
                    My client config look like this:

                    dev tun
                    persist-tun
                    persist-key
                    cipher AES-256-CBC
                    auth SHA1
                    tls-client
                    client
                    resolv-retry infinite
                    remote openvpn-server.org 443 tcp-client
                    http-proxy proxy-dns-or-ip.org 8080 proxy-uyser-and-pass.txt basic
                    lport 0
                    verify-x509-name "pfSenseOpenVPN" name
                    auth-user-pass
                    pkcs12 mirceass-TCP-443-SSL_VPN.p12
                    tls-auth mirceass-TCP-443-SSL_VPN-tls.key 1
                    ns-cert-type server
                    comp-lzo

                    And "proxy-uyser-and-pass.txt" is in the C:\Program Files\OpenVPN\Config. On the first line is username, and on seccond line is password, for proxy

                    Now it's working and I'm pretty happy.

                    Thanks all and have a good day!
