I set up PPTP VPN through our D-Link DFL-200 hardware firewall here at our company so that people could access network resources from home. The problem is, when at home, they can make a VPN connection just fine, but they can't ping the file server here at work, nor can they access or see any network resources. Our network is on a 192.168.1.x segment, with a 255x3 subnet. The server/LAN client that I am trying to ping has a 192.168.1.x address. The VPN server has a private gateway of 192.168.1.1, and public gateway of 66.x.x.x. On the VPN server, I have set it up to where it gives out 192.168.2.x addresses to any VPN clients connecting to it.
At home, my router's gateway is 192.168.1.x, the home PC is 192.168.1.x with a 255x3 subnet. The VPN client connection gives me a 192.168.2.x address with a 255x4 subnet.
I had a technician from D-Link test it on his end, and he was able to both make the VPN connection, and also ping the server and access network resources.
I think the problem with most people not being able to access network resources is because their local networks at home are on the same network id (192.168.1.x) as the corporate network (192.168.1.x). Traffic is not getting passed to the corporate network because the VPN client machine sees the destination as being on the local network. Is this what's happening?
Is there an easy way I can change something so that users would not have to get into their routers at home and start changing settings (most people are not that tech savvy). What I mean is, is there something I can do on my end here at our company. I should mention there are two NIC's installed on the file server that we are trying to get into from home. The one NIC is disabled. Can I do anything with this?
The server here at work is a Windows 2003 server, which is both running DHCP and DNS. The home users have XP operating systems. I've also tried disabling any firewalls on XP, and still no luck.
Thanks very much for your help.
