Enter Server LAN Network IP Address Mask:
This is the network mask of the Server LAN. For a class A network, it may be 255.0.0.0. For
a class C network, it may be 255.255.255.0.
Enter Server LAN VLAN ID (optional):
Note The VLAN ID is used for full 802.1q VLAN support.
Enter Server LAN Gateway IP address (optional):
This is an optional configuration that is used only if you are going to do SSL termination or
Layer 7 load balancing. Keep in mind this is an IP address assigned to the Server LAN
network interface. Be sure to use a unique IP address or duplicate IPs on the network will
occur. Enter 0.0.0.0 if not needed.
5.10 Common Configuration—For NAT, Transparent,
Single Network, and Out-of-Path Mode
Enter External Gateway:
This is the common setup for NAT, Transparent, and Out-of-Path modes. This is an address
on the firewall or router local interface. In NAT mode, the WebMux needs to know this to
route the server replies back to the clients. Although in Out-of-Path Mode this is not being
used to route return traffic back to the Internet clients, the WebMux uses this IP address to
check the connectivity of the external network on this gateway or through this gateway to the
ISP side routers. For SSL termination or Layer 7 load balancing, servers must route traffic
back to the WebMux via the server LAN gateway (previously mentioned). The WebMux then
forwards it to the client through the external gateway. If health check on external gateway is
enabled (by default), WebMux will turn the farm listing red to indicate the external gateway
failure.
