Network blocking UDP?
I use mosh (https://mosh.org/) to connect to some servers and have for years, which has normally worked fine, butfor the last couple of weeks it has not worked over the tmobile network at all, the UDP packets never reach their destination. I can SSH into the servers fine and run commands over SSH, but when trying to switch to mosh, which uses UDP, all UDP packets to the host are dropped and never received, while if I switch to a wireless network then they are received at the destination fine, and have tested over multiple different ISPs to different destination servers. Support are useless, as expected when it comes to asking indepth questions about networking protocols.
Need solution for T-Mobile blocking TCP
We have a coachmonitoring system that we need to transmit data to an off-site server. The gateway is connected via wifi, and the data is transmitted from the coach's dual-carrierrouter. The monitor works flawlessly when connected via AT&T's SIM. But, anytime we connect to T-Mobile, our preferred service, the data is blocked and we can no longer monitor our systems. I've been told the gateway uses a simple, old protocol of FTP and uses TCP port 8079. I have no idea how to fix this problem, but refuse to just quit out of ignorance.
