Best advise is to separate the functions. Let the firewall be a firewall and let a web server be a web server.

I ran into big problem because of conflict of ports between ISA and IIS. Thanks to Thomas W Shinder, Using the help given in http://www.isaserver.org/articles/2004ispcolo.html I could fix that but because Loopback adaptor has only one IP and I have many sites, all with their own public IP, how can I publish all my sites accessible by their own public IPs. One loopback adaptor's IP I have used in publishing default site defined in IIS. Can I re-run to make many IPs available to be mapped to public IPs what I did with one IP? Please help. Regards, John
