BindTo application filter for ISA Server
For some reason neither 2004 nor 2006 version of Microsoft ISA Server has an option for specifying the public IP address that will be used as the source IP address for outbound traffic (often called one-to-one NAT). Although this feature did appear in TMG Beta 2, not everyone might be able to upgrade. The only solution (besides upgrading to TMG) I could find is a piece of software from Collective Software called IP Binder. And that’s $220 per server. I say that’s a ripoff.
So I wrote an application filter that does just the same. Grab it here: BindTo. Feedback is appreciated.
