MiFi 500 LTE gets public IP but appears to be firewalled


Recommended Posts

I have mine through FreedomPop but I think Sprint is the one blocking it.  Since I don't have fixed internet at home I was planning to use my device to keep tabs on various things.  I port mapped my wireless camera through the built in firewall and still cannot access it from the public IP Sprint assigns.


After getting a Franklin U600 for free last month I tried the same thing out on the WiMax network, and it isn't blocked, camera works great. Has anyone got the LTE network firewall lifted and how do you do it?

I tested with FPs other devices they sent, a Franklin U600 WiMAX/EVDO modem.  It works just fine, both 3G and 4G network IPs are public and routable!


I'm thinking it might be the MiFi 500's router blocking things, going to acquire a Netgear LTE modem and move the SIM to see if I'm correct.

I doubt it is just the mifi router blocking them, unless you have a static ip or some type of business account, its very likely that sprint is blocking/filter incoming connections across lte to prevent lte from being used as a server connection.


wimax network is older and different and doesn't necessarily have the same filtering/network managemen rules.




I can ping my wimax hotspot public ip, but can not ping my netgear zing lte hotspot public ip.

    • Edit: Disregard, what I previously posted here was a previously starred bug.  
    • This convert site is funny to me. T-Mobile reserved a pole at this same intersection for a small cell in Dec 2017, finally installed it in July 2020, only for the small cell to be planned for decommissioning a little less than 1 and a half years later thanks to a convert site. It looks like the roof was rebuilt/re-enforced for the new setup too. The roof line is a little higher at the front of the building with new bricks.
    • Or, more simply, have a physical SIM that I can just move from one device to another.  Problem [already] solved.  Carrier doesn't have to be involved at any point in the process. I'll be among many (I'm sure) who will be glad to know if you see it.  Here in the DC area, Dish hasn't really done much yet.  I think I've seen some Dish gear around Richmond, but nothing here. - Trip
    • I like VICE.  They actually report on news no one else is willing to report. A lot of the places they go no sane person would want to be there.  They put their life on the line in many cases to get a story. From stories about the avocado wars in Mexico, being in the front lines against ISIS and Ukraine, to being embedded with terrorist organizations.   FAA might have some conspiracy 5G nut on their team or something.  At work ever year we have some one come in and say "hey, can you turn off the WIFI in my room? I don't want its radiation".  It doesn't make sense and their reasoning is always uneducated conspiracy. I can see someone coming into my office and acting crazy over C band disregarding everything else.
    • I think on esims it depends on how they implement it. If you can freely activate them on one phone while having it loaded on many that would be great.   I will let you know when I see Boost Mobile native 5g live here. So far no sign of even the plmn being active which I figure will be my first indicator. I look at changing networks with the TNX Sim and seem to get a full list of all carriers and their alternate plmns.
