Problems accessing sites when Source and Destination use same ISP's Static Addresses
This has been bothering me for a long time, maybe one of you can figure it out.
Say I am hosting a website from my server(same situation for VPN and other services), port forwarding is setup, it has a static IP Address. If I try to access it from a different location it work perfect, except if the different location is using the same ISP as I am, and is also running a static IP address.
(Example)
www.mysite.comĀ is using the static IP of 207.255.x.xx
Different Location 1 has a different ISP: result - Works fine
Different Location 2 has Same ISP - DHCP: result - Works fine
Different Location 3 has Same ISP - Static of 207.255.x.yyy: Result - Cannot connect
Different Location 3 has Same ISP - Static of 207.255.z.yyy: Result - Works Fine
To me it seems like a problem with the ISP's range of addresses.
Be happy to explain further if needed. Not an extremely urgent matter, more of an annoyance than anything.
Also too, the ISP has been contacted and it seems nobody there can figure it out either.

That's pretty much what I thought too, thank you for supporting my idea.
what's the subnet mask of those IP's ?
Just to know if 207.255.x.yyy and 207.255.z.yyy: are in the same network.
