Yes, I'd pretty much come to this conclusion when I read your reply. I
found a document talking about setting a reverse proxy to secure a web
server... is this what you were talking about? It looks like it would
provide a level of security I could be comfortable with.
My main concern is, I am not a 'security' specialist. I have employed
someone locally to assist me in securing our network and performing
quarterly audits, but I'd just feel better if we didn't have *any* holes
into our internal LAN. I guess I can live with two holes that are well
I appreciate all of the replies - saved me a lot of time trying
something that probably wouldn't have worked anyway.
