CTS HES-3106SFP-PLUS-DR, cant get any info

[orfeous1]

Hi!
My IPTV provider has provided me with a CTS switch so IPTV can be used.
But..

I want to get rid of it.
Ive tried a lot of things but most of them have failed.

Internet connected to WAN/TP5, LAN1 to my WAN router, LAN2 not used, LAN3 IP-TV, LAN4 IP-TV
If i dont connect to WAN/TP5 LAN1-4 does not get IP.
If i connect to WAN/TP5 to internet from the wall outlet i get different ips on all LAN1-4 ports.
LAN1 i see my ISP ip, LAN2 i get some kind of 172 adress, LAN3 and LAN4 i get 10.xxxxx series.

My goal is to get rid of this CTS switch and use my router instead and configure it somehow to be able to use IP-TV.
But i dont know if the provider configured it with all kinds of VLANS etc.. and if theyre tagget, untagged etc. if they are needed on the IP-TV ports or not.

Otherwise i should be able to use IGMP proxy and other settings..
Because i have the ip subnet i should be able to use that with a dhcp client on that port.
But if VLAN is involved its just a guessing game.

Though ive retrieved two VLAN IDs via my router GUI. Also some DSCP's
When i sniff on the WAN on my router with IP-TV and such connected.
But dont know if that is other equipment in the network that shows up. Might be.

If i reset the switch i can retrieve the default config per automatic. So i need to send in a ticket so they can re-deploy it.
Would be nice to somehow read the config text if it isnt encrypted or in hex.. etc..

Please help!
