point to point

dear all,

Help me in configuring my scenario

I have two adsl broadband connection in two of my offices with static IP.

57.xx.xx.xx location I
172.xx.xx.xx location II.
My local IPS are 192.168.16.1 to 192.168.16.15 location I
192.168.16.25 to 192.168.16.35 location II

I have assigned the Static IP for the adsl routers and configured DMZ to interface I on two MICROTIK AP RB 433.

I need further configuration steps to brdige both the lans together.

thank you in advance
