A client and I are trying to figure out why he can connect from his house using a Windows 8 computer to his company server using Navicat to manage MySQL through port 3306 he just opened and I can't using my Windows 7 computer from my house.
He is also able to open a remote desktop session, and I can't.
He can also establish a VPN connection, and I can't using the exact same settings.
He can also ping his server IP address, and I can't.
However, I am able to do all these things with other customer's as well as a data center I use, but I'm blocked from connecting to his company server. (The data center will open ports to specific IP addresses on request, which I've done to connect from my house.)
My client also has other employees who connect remotely to his company network/server as well.
The symptoms all seem to suggest a compatibility issue, as if there is some characteristic in my IT landscape that doesn't work with something in his landscape.
Does this sound like anything anyone is familiar with, or has a suggestion where to look next?
