Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.0 Build 20250428 Rel.18967

Hello,
how can I setup my router er605 for using 2 different vlan IDs on one WAN Port? I'm using port WAN1 for connecting to the fiber modem (ONT) from the provider. The WAN1 port has Internet VLAN 132 enabled.


I need for my Internet provider port 132 for Internet and port 232 for Phone. I have installed a avm fritzbox for the phone because I need a DECT connection. the fritzbox 7430 is connected to a switch  TL-SG3428MP v5.0 on port23.

I need some advices because I don't how to get this setup working! Thanks in advance!

Go to IPTV settings which allows you to set the Internet VLAN and other VOIP or IPTV VLAN IDs.

  @Clive_A Till this point I understood that if we use the IPTV option, we can split the 2 VLANS , one is Internet and another is VOIP. 

 

I have one ISP which sends INTERNET in VLAN 100 and VOIP in VLAN 200. I put the Fiber ONT in bridge mode and both the VLANs are tagged to the single LAN port of Fiber ONT. 

 

Say, I use IPTV and use the custom mode on WAN 1 and specify Internet as LAN 2 , 3 and 4 and LAN 5 is for IP-Phone. For the WAN 1, I configured PPPoE and mentioned the VLAN number 100. How would I get a DHCP address on LAN 5 since my VOIP runs through DHCP mechanism. I am unable to get this point. The DHCP option for VLAN 200 is not possible in Fiber ONT as it is in Bridge mode. There is no place in ER605 where I can mention that LAN 5 VOIP address needs to be obtained via DHCP from the ISP. 

 

So how to make this set up working ?

ISP require the PPPoE and VLAN ID, you input them in WAN settings.

Then go to the IPTV setting tab and input the VLAN for different purposes. 

IP are DHCP defined from the router. Not from your ISP. The router will NAT and distribute data for different purposes.
