Sorry, the configuration is actually :
/etc/hostname.em1 :
up

/etc/hostname.svlan1003 :
vlandev em1
inet 100.67.233.1/30
up
!route add 185.22.128.252/30 100.67.233.2

Network diagram :
OpenBSD(vlanid:1003) ---- Switch ---- (vlanid:1003)router --- 
client(185.22.128.253)

Thank you for the insight.
