I just wanted to put this out there to make sure I am understanding everything correctly around double NATs in an apartment building and if my solution is sound.
So I just moved to an apartment building, which includes internet as part of utilities (500mbps up/down). You plug your router into the ethernet jack in the room and you have internet...kinda.
Problem is I have a VPN server at home for when I'm traveling. Anytime I try to connect to my IP, the connection fails. All necessary ports are correctly forwarded, but all port scan tools time-out. So after some digging around and contacting the building's admin, it turns out they used dynamic NAT.
So we got that switched over to a static NAT and now my router uses the static NAT to grab an IP (public IP ->
However, no inbound request ever makes it to my system; all port tools continue to time-out on the ports I have forwarded. I removed the router from the equation and went directly wall-computer (setup with the static private IP,
10.XX), but still no success (rules out a router problem, right?). My questions are:
Is there anything else missing on my end that could cause this issue?
Could setting my ISP's equipment to DMZ any requests to my router solve the issue (not sure if that is the right network terminology)?
