Hello,
I would like to use OPNsense after a FritzBox 7560 as modem.
Unfortunately, seems like Fritzbox (Fritz!OS 7.01) has no Bridge mode where it runs as a modem only.
I think this is the reason why I have not yet managed to setup the WAN.
Question:
- What is the best setup here? Should I run FRitzBox and OPNsense as a "cascade of routers", or does anyone have an idea how to force it into Bridge mode? Technical support of my ISP mentioned to "reset" the Fritzbox and try then, but I could not get this up.
- Very likely I also have an open item with the Firewall rules - if I want to try if the internet connection works, I need at least a filter that allows for internet traffic to my LAN. I tried with a filter opening port 80/443 on the LAN, but I am not sure if that does the trick. As I am new to this: Which rule would I need to test if LAN->WAN->FritzBox->Internet works?
- Which setup for WAN is right? I tried FRitzbox with a static IP (192.168.0.1) and WAN with DHCP. Does this work, or do I need to assign Fritzbox and WAN the same address/mask? Thx for any guidance.
Highly appreciate your time,
Yours
Votan

Cascading is an option as long as you can actually manage the Fritz since you'll need the port forwarding done on each router - so it might get hairy fast.
Bridging would be the easier option - if that can be acomplished.

There is no official way of bridging a Fritzbox, there is a way but I would not recommend it, you need to export your config to a site, which changes some checksum etc. etc. (http://www.mengelke.de/Projekte/FritzBoxJSTool)
It does support 'exposed host' (DMZ), it should work fine in 99% of the cases.

You can use the Fritzbox in routing mode with additional PPPoE forwarding/passthrough (example with Fritzbox 7412 shown here (https://www.ip-phone-forum.de/threads/fritzbox-7412-als-modem-an-opnsense-andere-idee.297783/)).
