Is it the same LOR when you have ipfw disabled ?  (i.e. a LOR in 
ipdivert when you dont have ipdivert in the kernel ??) I ran into a 
number of problems with LORs in ipdivert 
(http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/86427)  I was able 
to avoid it by changing to pf and doing the natting there.
