Hi! This is my first post. Nice to meet you all, guys! Well, to the topic...
I don't know how common this is around the world, but here ISP typically force you to use their modem-router and do not give you access to the router menu. So even just to set up your WiFi password, you have to log in to their websites and change it there. They control everything. This is really annoying, especially because I can't even do port-forwarding that way.
So, what I initially did when I hired this ISP was to have them put their side in bridge mode and bought a new router that I plug to their modem-router. It worked like a charm, although it took me long and I had to learn a lot to understand this. Now they've suddenly changed the rules: they've removed everyone from bridge mode and instead, they put me in a DMZ, or so they say, and charge me to have a "public IP", as they say (it seems they're talking about something entirely different from what I understand as "public IP"). They gave me their DMZ IP: 192.168.100.200, mask: 255.255.255.0 and gateway: 192.168.0.1.
My router, when they made the change, continued to get connectivity, but my ports are no longer open no matter what I do. I noticed that my WAN configuration was set in "dynamic IP" mode (which worked with the bridge), but just to try, I changed it to "static IP" and configured it with the data they gave me. This still results in the same thing: connectivity=yes; port-forwarding=no. It looks like something at least is correct because, if I change the IP, I lose connectivity.
When I call them, they refuse to help me. They say this has nothing to do with them. It looks like they only want to give internet to people who only post cat photos in social networks. I have lots of doubts. For example, whether I should disable DHCP on my router. I tried it and what happened was that I lost connectivity and I couldn't even access the router menu. I had to reset it. Now it's working again. I don't have access to the ISP's router menu, so I can't change anything there.
I appreciate any hint on what I may be doing wrong or not doing or whether there is a key I need to consider. I know the information is vague, but that's precisely the problem: they are not telling me enough. If there is something else from my router configuration that it'd be useful to know, let me know and I'll post it. Thank!
