Configuring Health Monitor (TCP/HTTP) in DSR

When Layer 2 Direct server return (DSR) is configured, the HTTP/ TCP pool health monitor's destination IP is the VS VIP. For the Ping health monitor, the destination is the backend Server IP.

Following are the commands needed to configure on the server to make the HTTP health monitor work:

netsh interface ipv4 set interface "Ethernet0" forwarding=enabled
netsh interface ipv4 set interface "Ethernet1" forwarding=enabled
netsh interface ipv4 set interface "Ethernet1" weakhostreceive=enabled
netsh interface ipv4 set interface "Loopback" weakhostreceive=enabled
netsh interface ipv4 set interface "Loopback" weakhostsend=enabled

Where,

Ethernet0 = Management interface name

Ethernet1 = Data interface name

Loopback = Loopback interface name (VIP)
