Can't connect to server with my IP but can with VPN
I have a Centos7 dedicated server with cpanel and for some reason my developers can't see the websites on the server after they have accessed the server a couple of times.
This problem happens only with developers who access cpanel, ssh and ftp and not with customers who only visit the front end of the websites.
When the developers use VPN with German IP everything works fine but with Bangladesh and Indian IP we get this error message. All IPs that cant access the server are not in the black list cause I have checked in the WHM blacklist also with ssh command to see if the IP is on the black list. I have used csf -dr this command to remove from black list but it showed no included in the list. I have added the WHM black list image and the ssh command output image.

Hello, Are you using Host Access control or Country Code blocking through CSF? Ultimately if you're not able to access from a specific IP address this would be the result of some form of firewall either on the server or with hardware. You may also want to ensure that your provider isn't blocking the connection. I'd run a traceroute or mtr to the server to identify where it's being blocked. 0 -
Hi, First, PPTP uses a TCP channel on port 1723 for control and the GRE protocol to encapsulate data and create a VPN tunnel. The issue isn"t really PPTP itself, but GRE (IP protocol 47); GRE doesn"t use ports When trying to "port-forward" just port 1723 without having a router that knows the PPTP protocol (and also opens up for GRE), you may end up with some difficult issues, just like the ones you are experiencing. Do you have a feature in your router like "PPTP passthrough"? When trying to connect from the client, are you trying from an external Connection, or are you trying from "inside" to "outside"? Regardless of above, I would suggest that you look in to setting up SSTP (that are utilizing TCP/443) instead. 0
