Need steps to configure RB912 UAG as AP with 3G Upstream

RouterOS Beginner Basics

I have accomplished a few steps.

  1. Configured the 912UAG running as a HOME AP connected via ethernet and using DHCP on the main router (RB2011). Works great. Nice outdoor enclosure. Good signal strength.

  2. Added a Huawei 397B USB modem and got the PPP to come up. Negotiated the link to Bell Canada on first try. Simple setup.

  3. Tested successfully with a 24 volt POE injector to make sure I could go outdoors easily once I am ready to up to a roof top.


    Now how do I set the WAN/gateway to be the PPP interface so that I can use the ethernet and wireless on the LAN side?

I am guessing it is a simple process but I seem to keep shooting myself in the foot and getting disconnected in Winbox.

Is the default script (station mode) of any use to me? I don’t think so :slight_smile:

You need to NAT the PPP interface with:

ip firewall nat add chain=srcnat out-interface=ppp action=masquerade

Good advice. Thanks.

Link to ISP over 3G now working. I am thinking I might need a PPP mangle setting too even though it is working ?
