What are the minimum ports to be opened for access to parts of SBS 2003?

Would someone tell me what are the absolute minimum ports that would be required to be opened up in my firewall to allow the use of the following features of my SBS 2003 server:

- Remote Web Workplace
- SMTP and POP email access from external client
- Termial Services (RDP, not web client)
- Outlook Web Access

Any help is apprecitated!

I think you could get by with ports:  80 for web, 25 for smtp, 110 for POP3, 389 for RDP, and 4125 I think for RWW.

Here's some info from the same question on a SBS newsgroup:

>> RWW 443 and 444 if you want companyweb.
>> SMTP 25
>> POP3 110
>> RDP 3389
>> and OWA is best via 443, can operate via 80 but we prefer not to.

Those should be the only ports you need, for access as described above.
However, I would also enable DNS on UDP port 53 as otherwise you will need to use IP addresses instead of names to get everything working.
