Are there differences between ISPs (Swisscom, UPC, …) and their routers/modems when it comes to port-forwarding, IP management and so on?
Does anyone have previous experiences and suggestions, for which ISP I should go?
Edit for update 11.2023: Init7 with the 777.- a year plan has the option to add a 20.-/month extra for a own public, static IPv4. This was too expensive for me, i gave up and went with the cheap Yallo something, which has the whole GC NAT shenanigans. I now hope for better ipv6 support in the comming years… Mostly by the fucking shit mobile shitproviders 😡😡, mobile data by all isps in switzerand has NO ipv6 support
Should basically be possible with all of them. It could be that some ports are blocked by the provider, but this shouldn’t be an issue.
