are you looking to have RSS posted to your forums or to have outgoing capabilities for RSS from your forum?

While phpbb is not a quality product, it does have both abilities:
Do a search for a addon called "FIND" to allow for automated posting to your forum, or a search for "RSS" to enable outgoing RSS feeds.

For SEO from phpbb, just do a quick seo search on their sight as well.
