Interesting. I didn't know this.

Doh! Of course.

In fact, the second rule does appear in the fw2loc chain:
3159 229K ACCEPT 89 -- * * 0.0.0.0/0 0.0.0.0/0
0 0 ACCEPT 2 -- * * 0.0.0.0/0 224.0.0.22
But I still wonder why the
PARAM SOURCE DEST ospf
rule translates into:
6431 509K ACCEPT 89 -- * * 0.0.0.0/0 0.0.0.0/0
