I am running a CODA4680 in bridge mode connected to my pfsense 1100 (and yes it is getting a true public ip). I set it up the standard way, didn't touch the rules.
I performed an NMAP scan from my laptop tethered to my LTE hotspot from my phone and I see
I'm thinking there's maybe something with the LTE? Some device in my phone carrier's setup? Could the router in bridge mode have ports open? That would seem strange to me.
My firewall is not cisco, i don't understand why there would be ANY microsoft stuff on it so it's just weird
Even weirder is when I go on another (non-LTE) network and run the same command with the same target IP i get:
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn Nmap done: 1 IP address (0 hosts up)
So it's something on the LTE network that's doing something strange?
(Also yes, I made sure I'm running the scan on the same IP, it's not a DNS issue)
