How to transfer IPTV settings to Asus RT-N66U?

Question

ASUS

And so, my provider is so secret that in order to view IPTV you need to buy their router, they naturally password it. Two years ago I managed to pull the settings from it, and now I want to get IPTV working on my Asus RT-N66U router.
Settings from their router:

ifconfig:

firewall entry:

iptables -I INPUT -p udp -i vlan5 --dport 1234 -j ACCEPT

What can I configure on Asus RT-N66U:

And, of course, I can set the firewall rule. The question of correct vlan tagging interests more.

Answer 1

Judging by the first screenshot of vlans, there were only three on the provider's router (1,5,10);
1 default or control for provider access to router
5 goes to the first LAN port
10 to the second LAN port
You need to create 5.10 vlan in the router and specify the tagging WAN port of the router, untagget make port 1.2 for vlan 5.10, respectively. What did you have connected to ports 1 and 2 in the old router?
If the provider monitors its "household", then vlan iptv was most likely removed from your connection port ... But no one forbids you to try it :)
