How to use a Mikrotik as your router, but still leave the Verizon Fios router in place…
(sorry, no screen shots on this one just yet…)
Here are the basic steps you’ll want to do to leave the Fios router in place but be able to use the Mikrotik as “the router.”
- Change the DHCP range of the Fios router to 192.168.1.2-192.168.1.150. By default it will use every IP in the .1 subnet up to .254.
- Plug the WAN port of your Mikrotik into a LAN port on the Fios.
- Set up the Fios to give your Mikrotik a static DHCP reservation of 192.168.1.160.
- Enable DMZ on the Fios for 192.168.1.160.
- Turn off wireless in the Fios router.
- Plug everything into the Mikrotik – the only Cat5 coming out of the Fios should be going into the Mikrotik’s WAN port.
- Done. Now you can pretty much forget that the Fios router is even there. Just don’t change the IP scheme of the Mikrotik to use 192.168.1.xyz or you will run into problems.
- Extra Credit – set up your own username and login and enable remote admin on the Fios router. If you do this, make sure that a stupid login like ‘admin’ and ‘password’ is still enabled….it will be accessible to the whole internet.
Now you’ll want to make sure your Mikrotik gets the new IP address. If it doesn’t show up as 192.168.1.160 in the Connection List, then reboot it. That should force it to grab a ‘new’ DHCP address and should grab 192.168.1.160.
Using a DHCP reservation instead of setting a static IP in the Mikrotik means that if someone ever hits the Reset button the Fios router (it happens…) then the Mikrotik will just get a new DHCP address and won’t conflict with anything else on the network. After a reset the static DHCP rule will be gone, but the router will still work inside the home. You WILL lose remote connectivity to it, though, because the DMZ Host setting will go back to being off and the IP address of the Mikrotik will be different anyway… but that is a less critical issue than having an IP conflict that takes the customer’s whole network down because your static IP is the same as a DHCP address that the Fios hands out after a reset… ask me how I know….
Now your Mikrotik is ‘wide open’ to the internet. You don’t need to worry about any port forwarding or firewall rules in the Fios router at this point. Everything coming in from the WAN can pass right through to the Mikrotik.
Go into the Fios router’s Wireless Settings page. Click on Basic Security Settings on the left. The first thing on the page is a Wireless On/Off radio button. Click the Off and then Apply at the bottom of the page.
