ipnat & rdr?

[William Boettcher <wcboettcher_(_at_)_voyager_(_dot_)_net>]

Hello,

Everything with my OBSD 2.7 box is going good, with the exception of 
redirecting incoming mail on port 25 to my mail server. below is what I see 
when I type ipnat -l. It looks like the OBSD box is trying to redirect the 
mail to the mail server, but the mail server is not willing to receive the 
mail from what I see below. Is this correct? Or did I make a mistake in my 
ipnat & ipf rules? (Yes the public to private ip's are right, it's a really 
screwy network that will get ip's changed when time's available)
