Selectively seeing across 2 class-C IPs
Posted on 2005-03-04
An internal business network is on one class C -- 192.168.0.x and must have no internet access.
An internet "server" is set up on a 2nd class C -- 192.168.2.x -- which sees the internet fine.
This works perfect, because people on the internal network cannot get to the internet -- as intended.
But now they need to have it "both ways" -- meaning I need to VPN in to fix a system on the internal network on the class C not accessible from the internet.
VPNing to the internet "server" on 2.2 is no problem, as is VNCing. But I also now need to VPN into a 0.2 system to periodically fix it. No net access for the users of 0.2 MUST be preserved. Only I may get across.
There are several ways to do this, but I want other ideas before I go ahead. I already can VNC to a virtual link on 2.2 to that 0.2 system's hard drive, but that is not good enough. I'm thinking an app that lets me get across temporarily, directly to 0.2, with no permanent changes to the IP structure that already works great.
