I disable the firewall rule if I want to try updating the TV firmware.
I guess I can solve it but any pointers gratefully rec d
My current ISP has the cable modem completely locked down. No control over DHCP, no punching service ports through the NAT for home servers. Also they've got me double NATed.
In the USA and perhaps other countries the cable provider is required to let you use your own DOCSIS modem. The list of modems that work with their system has to be on their web site.
They don't want to do this because they are all shitheads and also because they want to charge you "rent". But TBF I imagine it's also because it's easier to debug customer support calls when they manage the whole connection (e.g. GF's kids complain that "WiFi is down" when they mean the cable connection is down).
Sadly, enforcement of this directive is up to each country's own regulator, and as the map in the above link shows, only a few countries have actually enshrined this in their national laws.
