I’m trying to get some use out of the Motorola modem/router combo wireless.
Hello!
Typically, when you put a modem/router/wireless gateway into bridge mode (modem only) you will lose the functionality of the router/wireless.
I am not familiar with the mg7700, but I do not believe it is an exception...

You might still be able to access the admin interface on the mg7700 when it is in bridge mode, but that is another topic.

@serbus - this cannot be stated in general!
one of the devices is only a simple modem in bridge mode, but there is an example this manufacturer (Sagemcom DOCSIS series) does not turn off wifi in bridge mode

Technicolor TG78.....series
there is a separate bridge mode which is delegated to the 4 ethernet ports and the wifi continues to work NAT-enabled++++edit:
the lesson is that it is manufacturer and possibly custom ISP CPE FW dependent -
I'm not sure how you could use the wifi parts of a modem/router when it's in bridge mode since it will not have a public IP itself.
I guess I could imagine using it to access the modem for admin purposes.
Even if it were possible in some roundabout way with VLANs it's impossible to recommend a setup like that unless you really had no other choice.
If you want to filter all your traffic through the SG-1100 put the modem in bridge mode and forget about using the wifi on it.Steve

Just a interesting information for everyone about what I mentioned above
it is an Altice Network solution on FTTH
ISP ONT + Modem / router (in NAT and bridge mode)in this case, the system has two public IP addresses:
- a public IP for the NAT-based router mode (IP phone + IP TV + WiFi, etc)
- a public IP (separated) for the bridge mode on port 4.....to pfSense
the two public IP addresses are not the same!!!
the ONT has an IPoE connection
-
Ah, two public IPs. Novel.
-
and all for the price of one IP (1000 / 500)
(clever things)
so no problem, with IPTV (multicast) + IP phone things work behind NAT on the other ports, separated -

I second this. I think you have to choose if you want it to be a modem or wifi access point. If your ISP is charging a modem rental fee, then replacing it makes sense. Put it in bridge mode, you'll most likely sacrifice the wifi capability, but you'll be avoiding that fee. If the ISP is giving you the modem for free, then use the Motorola as a wifi access point. Disable, all services like DHCP and only use the LAN ports on the Motorola. The LAN from the Motorola can go to Opt 1.

Thanks for the feedback. I bridged the modem/router and did lose WiFi functionality. So I returned it to routing mode and assigned a static ip on the LAN based on the Netgate’s MAC address. Now the modem is feeding internet through one of its LAN ports to the Netgate WAN. Netgate is still passing traffic with no visible issues. Then I enabled wireless on the modem/router so that’s forking out unfiltered traffic. As I am new to pfSense I have borked the system a few times and it upsets my wife’s Facebook activities and that gets her going on a tangent. So I am using that unfiltered wireless to provide internet to my wife’s devices. For the time being it’ll keep me out of trouble while I learn the system.
Again, thanks for the feedback.

This sounds like a good idea. I’ll try that out

Make sure to check with the ISP on the modem fee though. Because even ISP's that state the modem is "free", it never really is, they just include it in the cost. What I mean by that is unless you explicitly ask if there is a discount on your bill for BYOD, they will get away with billing you for that "free" modem. In other words, they should give you credit for your own device even if they're not billing you for their modem. If they don't offer credit, or they really aren't billing you for it, then wifi it up.
