We have configured two IIS servers as part of a web server farm that mirror
each other. In order to load balance the servers we have installed the
Microsoft Loopback adapter on each server, using a Virtual IP address,
that
our network load balancer uses to balance the traffic to the two real IP
addresses of the servers. This configuration works without issue until we
attempt to enable the Windows Firewall.
The firewall has been configured, using the security configuration wizard,
to allow the relevant ****ts for HTTP(S) and other services running on the
server. Direct connection to the server (i.e. not via the network load
balancer virtual IP address, but using the real IP address) continues to
work as expected. However, using the network load balancer virtual IP
address, the browser fails to find the server.
How can I get this configuration to work with the firewall enabled or is
this not possible?
Many Thanks
