There seems to be varying responses to this when someone on IRC asked on mas [1]. > Assume you have a /29 from the ISP that is routed to you via a > separate /32 link?

I wanted to avoid nat/rdr, however in the end binat-to is just so simple to use I question why I even went through the debugging process. Another win for pf being so simple, yet so powerful.
