openbsd routing logic confused by ip prefixes - correction

["=?iso-8859-15?Q?Jos=E9?= M. =?iso-8859-15?Q?Fandi=F1o?=" <openbsd@fadesa.es>]

Hello,

> I have an ethernet segment with different network prefixes, 
> concretely: 195.55.55.0/25 and 195.55.55.128/26.

sorry Łukasz , I wrote wrong prefixes, they are:
195.55.55.0/26 <- gateway block
195.55.55.64/26 <- BSD box
195.55.55.128/26 <- for future use
*195.55.55.192/26 is not mine.
http://www.ripe.net/perl/whois?form_type=simple&full_query_string=&searchtext=195.55.55.0&do_search=Search

and the problem explained below persist :(

So the BSD box has a interface in the second block (195.55.55.66) 
and the gateway is in the first block (195.55.55.1). All that I 
need to do is add a static route to 195.55.55.1, but OpenBSD
refuse to work with it. AFAIK it is a legal configuration and
using a test GNU/Linux box with this routing table works fine.

any suggestion?
