I'm trying to access my network at work from home. The sad part is, im replacing the network admin of the company and am the sole IT guy here. All the workstations have internal IP addresses. From the file/print/VPN server, I know for sure VPN/routing and remote access is enabled. My network has PPTP and L2TP as its protocols but from home I do not have the external IP address to enter the VPN. How do I find this out? There is a hardware firewall but I do not have access to it since it is password protected (predecessor did not leave documentation) and the manufacturer no longer supports it. It is a Netscreen 005 firewall device.
