Public IP and Port Problems

    I have recently signed up to a local WISP. I had one problem but now I have two. The internet is really good, and I don't want to bother the WISP as they are obviously very busy connecting people and are really just in it to provide a good service to people in the area.
    The setup is a TP-Link TL-WR841N Router which I connect all of my devices to via either wifi or onto a powerline network that goes upstairs. The WAN port of the TP-Link router is connected to a microtik device on the roof running RouterOS v6.34.2. I have full access to the tp-link router and can use those settings but I have no access to the microtik device on the roof. I can get to the login page but that's it. I don't really want to go any further than that on the microtik device as to not mess with the isp's settings. It looks something like this https://img.routerboard.com/mimg/752_l.jpg

    My first problem is that I can not port forward to e.g. access my printer webpage from outside the network, use wake on lan, or use an ftp server from my pc. If I type my public ip into the address bar it comes up the ftp of the microtik device, not my own. I tried putting some of my devices as the DMZ, tried port forwarding via the virtual server section of the tp-link device and nothing is working. To me this is only a minor problem to the second but it is a bit annoying that I do not have control over the ports etc.

    The second problem I am having occured in the last few days. There has been some sort of change to my public IP address. It comes up on almost everything as what it has always been for months. Obviously I am not going to put it here. I watch videos on some sites that make a video available to a certain public ip for e.g. 6 hours. My problem is that when I go to watch the video it comes up wrong IP and does not let me watch it. The public IP I see on the websites that show it, and on speedtest.net show up as what it has always been but for some reason google when I search for my ip comes up as something completely different, which upon looking is from a VOIP and Internet services provider. Not my ISP. I only noticed this in the last few days and I have a feeling it is affecting watching videos etc. The IP google shows up is completely different to what it should be. Could the videos and public ip change in google be connected?

    Thanks in advance for any help with this. It's really annoying.

    The Mikrotik is routing. You'll need to contact the provider and get them to bridge it, they will then give you the PPPoE details that you add to the WAN port if your TP link. Looks like you have a dynamic IP that changes every few days, they'll most likely charge you for a static one

    Thanks for that. I know I do have a dynamic IP. The weird thing is almost all websites pick up my ip as the one I have always had and the owner when searched for comes up as my isp, but others such as when I type what's my ip into google come up as a completely different public ip not from my isp but from a voip and internet services company?? It's strange

    Neither of those IPs are assigned to you. They're shared. Depending on where you're going a different router in (Imagines?) network will be doing the NAT so you'll appear as it.

    The Mikrotik you're hitting is probably their high site.

    Do you really want to be exposing ftp servers and your printer to the public internet?

    Nope, definitely mine as the only control I have over it is plugging it in and out. I can access it through it's IP in the form 192.168.XX.1 and my tp link device is assigned the WAN IP of 192.168.XX.2 The default gateway on the tp-link device is 192.168.XX.1.

    As for my own public ip, how do I get that? Doesn't everyone have their own public ip? Also, I'm not with imagine. It's an isp running on a much smaller scale but they appear to be connected into the network of another isp that is much larger.

    I won't be using ftp servers etc. over it, they were just as examples as I am not sure what would help someone answering the question or what wouldn't. Anything I would use over it would be password protected e.g. access the router or an ip camera.

    Not always, it depends on the provider. You could be using a local ip and sharing your pubic IP with others.

    The IP does offer an option for a free static ripe ip. Would that me my own personal one?

    You should look into accessing your network from outside via a VPN. With password login disabled and just using private keys. Once connected you'll be able to access everything as if you were connected at home, and you're not exposing anything to the public internet.

    I'd say if you had a password login for your IP cameras publicly available you'd end up with massive amounts of traffic attempting to log in constantly
