[Q] Port Forwarding Router when Modem cannot be placed in Bridge mode

[JoshJ5Hawk]

Good evening everyone,

I'm not quite sure how to phrase this right so please ask followup questions if I'm not making any sense.

Here is a quick/sloppy Topology image

So basically I have my Modem in the basement, an Arris SBG6580, which cannot be placed into bridge mode, because there are devices in the basement that need to be connected to the modem (unable to route any other cables) (IP is 192.168.0.1) Now, I thought I'd be super clever, Why not put my router that is upstairs (Asus RT-AC87R ip 192.168.0.3) into the Modems DMZ, then my server PC (192.168.1.10) in the Routers DMZ (That was an initial test, intend on going specific ports once I'm up and running) Well that seemed to work for a short period of time but now it no longer does.

I have an additional (older) wireless router, that I believe I can make act as a dumb switch (DD-WRT I believe I read?), if that will help.

Again, I apologize if I'm not being clear, I hope the image above helps describe my situation.

Thank you in advance
-Josh

I'd recommend testing the particular port needed for your server (especially if it's a web server) to be sure it has not been blocked by your ISP.

Also, placing the server in a DMZ without firewall protection is usually not a good idea, since the server will be completely exposed to malicious attacks.

You could solve the issue by configuring the Asus as an AP and performing port forwarding functions from the Arris only.

I'll give that a shot bud, thanks! I did have the webpage working before (along with TS but both stopped working simultaneously. Will configuring the Asus as an AP still allow it to function properly both wirelessly and via ethernet?

Sorry for the late reply.

The answer to your question is "yes". The Asus will still have full wifi and wired functionality.
