Static routes issue

["Dante F. B. Colò"]

Hello everyone

I'm trying to setup some static routes on a freebsd  box for some public 
addresses , the machine has two ethernet cards *em0 *and *em1 ***, *em0* 
is attached to a Cisco internet router and *em1* is connected to a 
switch, both interfaces have  public addresses of the same range , *em1 
*appears has absolutely no communication  ,  i took a look at the static 
routes and there is a route for the subnet that it goes to *em0* , i'm 
trying to add a static route for the ip address pointing to the***em1 
*without pass gateway using *-iface* parameter but always returns 
"Network unreachble", someone can help me or give some tips to address 
this  ? for many here this is probably a nooby question, we also have 
some firewall Linux boxes that i'm gonna migrate to freebsd (also trying 
on openbsd with the same problem) but first i have to solve this.

Best Regards
