ipv4
2 TopicsWith happiness, why has FTP started to work with T-Mobile home internet?
I've had T-Mobile home internet several months now. Having made it through severalissues I'm glad I stayed with T-Mobile. Because T-Mobile maps IPV4 over IPV6, FTP did not work. To use FTP I had to subscribe to a VPN, turn it on when FTP was needed then turn off again. I've been using NordVPN for that. However, just now I attempted some file transfers and they worked! All my FTP logins work without using the VPN. This is wonderful. So I'mwondering if anyone knows what changed. Was it T-Mobile? Was it something else? It isn't the FTP servers or protocols or the internet in general. I use multiple FTP servers. So it has to be T-Mobile.320Visto0likes2ComentariosSolving CGNAT problems?
AFAICT my T-Mobile Internet router connects to a CGNAT DMZ, and every time I connect to a networkservice I do so from what appears to that service to be a different IP4 address. There seem to be exceptions, however, for some known protocols - I've had an SSH session up for several consecutive days. So one CAN obtain a static IP address for things like VPNs and SSH, but the protocol has to be well-known. Therefore, questions: Is there an IPV4 packet flag that says "this session needs a static IP address" to routers along the way? Routers are already reading the port assignments in order to determine "oh, that's SSH, better make this static." Is there a packet flag one can set? If I turned off IPV4 and just used IPV6 would the CGNAT DMZ provide a static address, since I wouldn't need to be sharing IPV4 addresses any more?802Visto0likes2Comentarios
