Routing between different subnets

Hello,
I have a router (6.9/amd64) with NATed subnets (vlan425, vlan426, etc..). This box is also connected to another subnet via vlan43 and the box can ping gw of vlan43 and machines inside this subnet.
I need to enable access for clients from vlan426 to machines in vlan43 .

I have no idea how to achieve that...

I've tried to add some routes to /etc/hostname.vlan426:
!sleep 2
!route -v add -inet default 10.4.26.254
!route -v add -net 10.43.0.0/16 10.43.0.197
but /etc/netstart stucks with these lines...

What am I doing wrong?

My configs:

$ cat /etc/hostname.em0
-inet
inet A.B.C.D 255.255.255.192 NONE

$ cat /etc/mygate
A.B.C.1

$ cat /etc/hostname.vlan426
inet 10.4.26.254 255.255.255.0 NONE vnetid 426 parent em1

$ cat /etc/hostname.vlan43
-inet
inet 10.43.10.197 255.255.0.0 NONE vnetid 43 parent em1
!route -v add -inet default 10.43.0.1

$ grep 10.43.0 /etc/pf.conf
pass quick from 10.4.26.0/24 to 10.43.0.0/16
pass quick from 10.43.0.0/16 to 10.4.26.0/24
