Valid reasons, all.
I don't see any benefit to using multiple external IPs to reach the same
internal server using the
same protocol.
You can use a single IP and let the web server hostheader filter figure it out.

For couple of reasons
1.Web servers have certificate and to use web publishing I have to go through
all the complicated
configuration of moving certificate to ISA and configure ssl bridging.
2. Most of these sites don't have much cacheble objects
Currently I don't have any url filtering on web server. I should do that.
But do you think that server publishing with multiple ip addreses on ISA mapped
to multiple sites on
web server(host headers) is not a problem, or is good confiuration to work with.
Thanks for your help.

Since you're using server publishing, you lose all the URL filtering that Web
publishing provides.
You should install and configure URLScan on the web servers to replace that
functionality.
Why are you using server publishing?

What are you using; web or server publishing?

Any suggestions on this one??
Thanks
All
I have 2 ips configured on external NIc of ISA and have them mapped to one ip
on the internal web
server which is hosting multiple web sites using host headers. It works fine as
I performed a test,
but just want to make sure that there is no problem doing this.
Thanks
