Internet gateway is a host (or a server) at the boundary of LAN and the Internet. It is the machine where WinRoute will be installed (refer to chapter 2.3 WinRoute Installation).
TCP/IP parameters of the Internet interface must be set according to information provided by your ISP. The following parameters are required for proper functionality of the Internet interface: IP address, subnet mask, default gateway and at least one DNS server's address.
The web interface of the company headquarter's firewall should have a fixed IP address to make it possible for the filial's server and VPN clients to connect to it (see requirements in chapter 1 Introduction). Suppose that the ISP has aasigned IP adddress 63.55.21.12
. It is also recommended to assign a DNS name (e.g. kwf.company.com
) to this IP address; otherwise all VPN clients will be required to define the server by the IP address.
Verify connectivity (i.e. by using the ping
command or by opening a Web site using your browser).
The following parameters will be set at the LAN Interface:
IP address — we will use the 192.168.1.1
IP address (refer to chapter 2.1 Selection of IP addresses for LAN)
network mask — 255.255.255.0
default gateway — no default gateway is allowed at this interface!
DNS server — for proper functionality of authentication in the Active Directory, the particular domain server must be set as the primary DNS server. Use the Preferred DNS server entry to specify the IP address of the domain server (192.168.1.2
).
