IIS Web Server NLB IP limitation

We are close to the limit of IP addresses on our IIS Webservers using Microsoft NLB load balancer.

(Server 2008 Std IIS7)

We can have 16 un-load balanced IP addresses on each of the webservers, and 16 load balanced IP address between them.

We have to use a new IP address per client site as SSL is required.

I am looking for a simple solution so we can add more IP addresses.

Can we add a second NIC to each webserver - not part of the load balancing and add additional IP addresses to the extra NIC?

Ideally I would like it to be on the same subnet? - is this possible?

E.g. . Nic1 192.168.4.x part of NLB Nic2 192.168.4.x not part of NLB.

Failing that we could add Nic2 to be on another subnet e.g. 192.168.5.x and then add new sites on to this NIC?

is this possible? The web servers are virtual and so adding additional resources and Nics is not an issue.

thanks in advance.

Are these bare metal or virtualized?

Hey there, I have decided against dual NICs as we were getting DFS replication errors and some SQL reporting tools were failing too, too much of a headache.

Thanks for everyones help.

The reason I ask about virtualized is the free esxi from VMware can load balance easily with multiple nics
