• Both WebMuxes connect to the Router LAN, and to the Server LAN. Each WebMux
interface has a unique IP address.
• The registered Internet IP address range is a class C address range.
• The IP address of the WebMuxes’ Virtual Farms must be in the same network range
as the Internet router.
• The WebMux translates the Router LAN IP addresses to an internal non-routable
class A address. In this example, the subnet-mask is 255.0.0.0. The IP address of the
WebMux interfaces attached to the Server LAN are 10.1.1.10 and 10.1.1.20.
• The Default Gateway for all the servers is 10.1.1.1.
• Farm 1 IP address is 205.133.156.200.
• Servers 1 and 2 serve Farm 1.
• Farm 2 IP address is 205.133.156.210.
• Servers 2 and 3 serve Farm 2.
• Changes to the servers: change default the gateway to 10.1.1.1, as well as the IP
addresses to the 10.3.1.10/20/30 addresses. If on the server there is a service attached
to the IP address (HTTP/S, FTP, etc), please make sure the service will run on the
new IP address.
Note Although the WebMux can work with any IP address range, all server IP addresses
should be Internet non-routable address so that the source address from the Internet does
not conflict with the IP addresses on the Server LAN.
Note If there is a firewall between the WebMux and the Internet Router, a rule must be
defined in the firewall to allow the IP address of the WebMux interfaces on the Router
LAN in addition to the farm IP address (could be same as the WebMux Router LAN IP
address) to communicate out to the Internet on all ports. Since the WebMux is doing
Network Address Translation of the farm address to a non-routable address, the farm
addresses on the WebMux must be able to communicate outbound on all ports defined in
the farms.
