If you're using a DHCP server to assign IP addresses to clients, there are a couple of other problems that could cause users not to be able to go beyond the VPN server. One such problem is that of duplicate IP addresses.

If the DHCP server assigns the user an IP address that is already in use elsewhere on the network, Windows will detect the conflict and prevent the user from accessing the rest of the network. Another common problem is the user not receiving an address at all.

However, there are situations in which an address assignment fails, so Windows automatically assigns the user an address from the If the client is assigned an address in this range, but this address range isn't present in the system's routing tables, the user will be unable to navigate the network beyond the VPN server.

If everything seems to be working well, but you can't seem to establish a tunnel between the client and the server, there are two main possibilities of what could be causing the problem.

The first possibility is that one or more of the routers involved is performing IP packet filtering. IP packet filtering could prevent IP tunnel traffic. I recommend checking the client, the server, and any machines in between for IP packet filters. The other possibility is that a proxy server is standing between the client and the VPN server. A proxy server performs NAT translation on all traffic flowing between the client and the Internet. This means that packets appear to be coming from the proxy server rather than from the client itself.

In some cases, this interaction could prevent a tunnel from being established, especially if the VPN server is expecting the client to have a specific IP address. Can Russian hackers be stopped?
