Hello everyone. Long time youtube channel viewer and sub, first time forum poster. I was looking for some help or direction to a video or post if it already exists. First some background. I sold my home and moved back in with the parents right before the world ended (unrelated to the quarantine). Now I find myself and my network all bunched up in my bedroom upstairs which is fine. I like having everything around me. We added a MoCA adapter to get more reliable internet upstairs. There was just a cheap Netgear N repeater before and my sister suffered. I had experience with MoCA towards the end of my cable career for 11 years. So far, so good, internet access is great now but I really want to separate my stuff on the network. So the issue is I am close to finishing my new, custom Plex server and with my stepfather’s current network settings, my current Windows based Plex server is not able to be view outside on WAN. I did ask about opening a port which I know ultimately needs to be done but I could sense his apprehension (both from the potential vulnerability in his network as well as not knowing what exactly what I need done and how to do it in his pfSense). He and I don’t always see eye to eye on certain things [he hates updating anything because everything is working, despite potential serious security issues] and I’m hesitant to press the issue until I have a plan. He was open to it and said we can talk about it. He’s fairly tech savvy and a good programmer but I think he knows just enough when it comes to certain things like networking. I’m not a network engineer by any means, I have no formal education. He was able to put together a pfSense router after he was impressed with mine. He wasn’t aware of things like MoCA and pfSense before I introduced them to him.
So with that context, my little network includes my currently un-powered pfSense box, a WD EX4100 (24TB) NAS and PR4100 (48TB) NAS, a Win 10 HTPC (current Plex server), my new [empty] 80TB dedicated unRAID Plex server, FireTV stick 4K (with ethernet adapter), a single Silicon Dust HDHomeRun Connect Quatro OTA tuner, all fed from my 24P switch connected to the first port of the MoCA adapter plus misc wireless devices (smart plugs, Echo Dot, Harmony Hub, and LED light controller). Plus there’s my Unifi LR AC AP (off the 2nd port of the Translite TL-MC84 MoCA adapter). What I’d like to do is boot my pfSense box up and feed that from the MoCA adapter. I know it’s not ideal but would love to isolate my stuff that way he can set me up on a VLAN so I can have my own path out to the world. That’s where I need help. What’s the best way to configure a double NAT pfSense situation on purpose and not just for making a tutorial video (private IP for WAN IP). I don’t have a smart switch and know that’s probably the simplest solution, I really would like to have my pfSense running so I can play and learn without disturbing the rest of the network as my stepfather is now working from home and my mother will soon be returning to working from home. I want to be able to look up and have control of my own device IPs and be able to set my own statics. I want to have a good plan before asking to open up a port for me again. It really is a strange feeling to not being in control of certain network aspects. This living situation isn’t permanent but I wanna be comfortable without getting too comfortable if that makes sense. I just want my things to work like they did at my old house until it comes time to move out. Thank you in advance for any advice.
