DMZ not working

[Blayer98]

Ok, Idk if I’ll ever be able to fix this issue, I’ll probably end up stuck with double NAT issues, and I can’t put my main router on bridge mode otherwise there’s nowhere for the packets to be sent...

You want the second router set up as a switch. How to do this varies by router, but here's the general idea: https://www.techwalla.com/articles/use-router-switch

I have already tried this.

Using Access Point mode will hide the DMZ options, and even WITH this, I still cannot get DMZ on my main router for my Dreamcast. The Pi and the Dreamcast share the same MAC Address like I mentioned previously (I think I did, can’t remember.)and I cannot enter the Dreamcast’s IP Address because my TalkTalk HG633 router doesn’t work that way...

Ok, so I found out that what I have to do is DMZ my Dreamcast on my TP Link router, and then I also have to DMZ the TP Link router on my HG633 router which is ridiculous! If anyone knows of a much easier way to do this I’d really appreciate it!

and what is the difficulty, it is very easy to do
P.S. some TP-Link models do not want to forward packets to DMZ if SPI firewall is enabled

What do you mean by “SPI Firewall”?

I know it’s easy to do and if anything is actually a lot quicker, but I’d rather not have to make the router DMZ’ed as that also exposes the DreamPi I’m using...

DMZ open ports to your dreamcast, not DreamPi
but if you are so worried, instead of DMZ, you can configure port forwarding manually for each game

I literally said that I have DMZ'ed my Dreamcast. I did so on my second router because I can actually specify the Dreamcast's IP Address. I can't do that on my main router, again as I said earlier, because my HG633 Router doesn't work that way and will only allow me to dmz the pi because both the dreamcast and pi share the same mac address.

1) what model of your TP-Link router?
2) how do you connect TP-Link to HG633?

TL-WR940N. I'm able to specify the Dreamcast's IP into DMZ, but it won't work on it's own, I also have to DMZ the router via my HG633 router. It also does not have Internet access on it's own. I cannot use bridge mode on my HG633 router as the packets will have nowhere to go at all.

I connect the TP Link router via Ethernet to my HG633.

I connect the TP Link router via Ethernet to my HG633.

a few more questions and I will be ready to give you step-by-step instructions
1) TL-WR940N has multiple hardware revisions, which revision do you have?
2) which LAN IP is currently installed on TL-WR940N? (IP for accessing the WEB interface)
3) what is the LAN IP of the HG633 now? (IP for accessing the WEB interface)
