I'm on my mobile so I'll try and keep this succinct while giving as much Info as I initially can.
We have Lenovo laptops in our business all with a standard setup. One particular colleague is simply unable to connect to our corporate VPN and I've tried literally everything I could think of. Everyone else in our organisation are connecting fine so the VPN server is up and working.
Interesting thing is that this colleague started experiencing problems as soon as he joined a new ISP. This ISP is called Comcast and based in the US. I've read some anecdotes that they are blocking VPN but this is not substantiated on their website.
Anyway, I asked him to try and connect from another network/ISP and sure enough, he could connect to our VPN with no problems at all from a Starbucks. Technicians at Comcast are adamant they do not block VPN but that they also don't support VPN setup and VPN Application support which is totally fine, that's what my job is for. Though recall our VPN works as everyone else connects fine.
I've gone so far as to open port 1723 (TCP) for both directions on her router though I know this is gratuitous as I've never had to do this on the client side, this is a requisite on the server, not the client right? Am I missing something simple or perhaps something intricate?
