How do I separate a switch port for vlan "vlan6"?

    Hello there,

    Please forgive me my disorientation but since I've installed DD-WRT and started playing with vlans, I realized just how lame I was. I am. I need help with setting up a specific vlan configuration to break my ISP's monopoly for routers in Lithuania. Basically, the story is quite simple:

    My ISP provides Internet and IPTV. As it all goes through optic fibre -> fiber/T converter (ethernet) -> router; there's no pppoe or pppoa or anything like this. Plain old ethernet. But they wouldn't let anybody get their own router or tell how to configure one. They force clients into buying one from them for crazy price. Anyway...

    My goal is to use a non original (not provided by the ISP) router and still be able to enjoy internat and IPTV.

    Here's a scheme of what goes through the cable:
    TEO - Lithuanian Telecom
    Zebra - ISP, Division of TEO
    MGMT - Some sort of management access to the original router (I suppose)
    GALA - IPTV service
    IPTV STB - Set-Top Box (Sort of a decoder if you wish) plugged into an ordinary TV 
    As you've noticed, IPTV goes as Vlan6. Correct me if I'm wrong but that should mean that the ISP sends the IPTV packetrs addressed to vlan6 and creating a vlan6 on my router and dedicating one switch port for it should do the job, right?

    Should you be really in a mood for helping me out - here is my old (original) router's config file. Ignore the adsl part as the RJ-9 port is not in use at all.

    1. Please tell me... is my assumption right?
    2. If it is - could you please tell me the commands I need to type to have switch port 4 configured as vlan6 (tagged, I suppose - if that's what tagging is... I mean if tagged means that it will be accepting packets "marked" as vlan6 than yes, that's what I probably want ;))
    3. Do I need to modify firewall settings?
    4. Just so you know - I'm using DD-WRT backfire. And I don't exactly have a linksys - I have a TP-Link WR1043ND - but (another assumption) it should work on it, too...

    backfire is OpenWRT - not dd-wrt!
    Watch out - there are two types of "vlan", one is used internally in a Broadcom router to separate out the 5-port switch into sub-switches for LAN and WAN. The second type is "vlan tagging" which can be applied to external Ethernet comms using the IEEE 802.1Q header.

    Hello again,

    You're absolutely right. My mistake. I was trying to do it with openwrt backfire a week ago. Now it's DD-WRT v24-sp2 (08/07/10) std

    So... What does it practically mean?

    That I need to set up both? push all the traffic addressed to vlan6 to the switch vlan on port X?
