very much so, by default, all the ports Outlook needs to connect to Exchange are blocked by default on a firewall. I don't advise changing this behavior. Besides, if Office 2003 is on XP with SP1, then you can allow RPC over HTTPS with Outlook, without compromising security on your network. But only in the above configuration is this supported.

That's what I'm saying, opening RPC to the outside world is a huge security risk, DON'T do it. "RPC over HTTPS" is a new feature with Exchange 2003 and Outlook 2003 ONLY.

A VPN will allow the client to come in with further holes in the firewall. Personally, I'd use OWA over Secure HTTP, the new OWA is very functional creature, I haven't found much I cannot accomplish with it in comparison to Outlook.
