Quoting setagllib@optusnet.com.au (setagllib@optusnet.com.au):

> rdr ex0 0/32 port 6891><6900 -> 192.168.1.3 6891><6900

Your '6891><6900' part on the right of '->' has to be a port spec.

portspec       = "port" ( number | name ) [ ":" ( "*" | number | name ) ]

Read pf.conf around line 652 for the explanation. So your rule should 
probably look something like:

rdr ex0 0/32 port 6891:6900 -> 192.168.1.3 6891:*

The other problem is harder to tackle. Have you tried dumping a bit
of information to find out what happens?
