Informasjon om Altibox IPTV oppsett med egen router
Jeg fant på https://forum.openwrt.org/t/help-getting-iptv-working-with-the-altibox-isp/38063/24?page=2 litt informasjon som jeg har skrevet om litt etter informasjon fra @trrunde (diskusjon.no).
The requirements for forwarding Altbox IPTV and Internet between fiber (with SFP or media converter) and a shared lan with both STBs and Internet clients are simple:
* tag VLAN 101 (IPTV) and 102 (Internet) on wan
* clone mac address of ISP gateway/router on the wan.101 interface
* run DHCP client on both wan.101 and wan.102
* SNAT/masquerade between lan and both wan interfaces
* igmpproxy between wan.101 (upstream) and lan (downstream)
