The remote computer refused the network connection. phrase has been my arch enemy for the past week now
I recently "bought" a VPS server, I gave up trying to configure it with OpenVPN, all the issues were making me lose my mind, so I tried the easier way with pptp, but i figure, both are leading to a dead end...
I followed this post (many others too but this is the unlucky one), http://blog.secaserver.com/2011/10/install-vpn-pptp-server-centos-6/ and it all goes well with the setup, however, I run into this error when connecting to the VPN in Windows 7
here is a pic of the error: Image
So I do not know what I have done wrong...
When connecting,
Code: Select all
netstat -apn | grep -w 1723
before connecting:
netstat -apn |grep -w 1723
tcp 0 0 0.0.0.0:1723 0.0.0.0:* LISTEN 1137/pptpd
after the error came I tried again:
netstat -apn |grep -w 1723
tcp 0 0 0.0.0.0:1723 0.0.0.0:* LISTEN 1137/pptpd
tcp 0 0 41.185.26.238:1723 41.13.212.47:49607 TIME_WAIT -

I check the iptables, everything is normal, all INPUTs, etc are before rejects, username and password I also checked in chap-secrets file, I am really puzzled...
