I have two shops and the office. Shops are connected to the internet via same internet provider, but they are in the different parts of the city and use different connections of course. This internet provider uses NAT so my both two shops have the same externally visible IP address.
Office is connected to the internet using different provider and has static IP.
The text here says
The PPTP protocol does not allow two VPN connections from the same remote IP address
Is that really so? Is this a physical limitation? I've tried to connect to the same PPTP VPN server from home where my both notebook and laptop are connected to internet using one router. Both connections from both machines were successfully established.
Is there any problem in the situation where two devices connect to the same VPN server and have same external IP? I need each of my shops to see office network and office network to see each shop's network. There is no need for the shops to see each other.
