Re: Is ISA recommended when using OWA or RWW?

That's helpful, thanks. Just one NIC as I’m recalling now, though it would be easy to add another if it's worth it.

It's behind a DD-WRT driven router. I'm not sure that would qualify as a good firewall, exactly. SBS's firewall is running as well.

It makes sense that port 80 isn't needed, though I often see it cited for some reason (as if anyone wouldn't use https). Someone in the Technet forum listed these for a "full boat" configuration:

ip/47 (GRE)
tcp/25 (SMTP)
tcp/80 (HTTP)
tcp/443 (HTTPS)
tcp/587 (SSL SMTP)
tcp/993 (SSL IMAP4)
tcp/1723 (PPTP VPN)
tcp/3389 (optional RDP, but helpful for remote admin; especially if you are just getting started out and don't have the VPN working yet)
tcp/4125 (RWW)

If you have a 2NIC setup ISA is really the way to go. With a 1NIC setup you should have a good firewall in front. You do not need port 80. 443 is used for OWA and 4125 for RWW.

I have SBS 2003 R2 SP2 and am on the verge of implementing OWA or RWW. Under what circumstances should I consider also installing ISA 2004 and using it in conjunction with these? The standard procedure for enabling OWA/RWW really doesn't get into ISA that I noticed, so I imagine going without it is OK, but it would be helpful to know more about when it would be worth the extra trouble of implementing it for this specific purpose.

Also, do all these ports need to be opened on the router for OWA, or can I get away without one or two: tcp/4125, tcp/80 and tcp/443?

Thanks
