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 (IP adresa 192.168.1.2
).
