You can do this; just point your DNS server "A" records to the virtual IP and run with it. Bear in mind, though that it's not "supported" by the ISA team.

So Iam using host headers and port 80 for the first connection but secondary connections are secure connections using 443. Each web server is firewall client. I want to configure fault tolerance on extenal side of ISA using NLB but was not sure how should I do it and how should I configure our external DNS for this.

You don't mention whether or not you're listening on a "per-IP" basis, so I can't say if NLB is of any use to you.
