Hi, Yep - ISA can operate as a web filter, to restrict which external websites your on-campus users can access. Think blocking porn etc. But in this context, ISA is deployed to protect a local exchange server from malicious incoming external traffic, whilst hopefully allowing good external traffic to come in. In other words, acting not as a regular web proxy, but as a reverse proxy. (with application level filtering). -- Chris Edwards IT Security, Computing Service University of Glasgow, charity number SC004401
