I’ve enabled the PPTP server on my Balance 20 running firmware 6.1.2 and I’ve connected a client (hereinafter “the remote host”).
I see that the remote host, which of course lives outside my LAN, acquires an IP address from my DHCP server and from within my LAN I can ping (and connect to) the remote host. This is good. This is why I wanted to set this up.
However, the remote host CANNOT ping (or connect to) a host on my LAN. This is actually a good thing. I like this. I probably would have chosen to configure things this way. But it’s not what I EXPECTED. I would have thought one of the main reasons for many people to enable PPTP would be to enable the remote host to “see” hosts on the LAN.
I would like to understand why the remote host cannot “see” hosts on my LAN because I want to make sure I understand any security issues involved. If there’s a switch I can throw to enable the remote host to “see” hosts on the LAN, I want to know where that switch is and I want to toggle it and observe the difference in behavior so I’m convinced everything is set up correctly.
