mimicing DIR615 with RB2011LS

Hi All

I’ve recently replaced DLINK DIR615 router (which I’ve used for IPTV with DUNE STB) with shining sparkling RB2011LS. Although I know RB2011 is more than capable doing igmp proxy, I still want to have the same setup I had with DLINK.

With DLINK I had sfp port connected to provider and getting dynamic ip using predefined MAC on this port (provider gives oot ip only to designated client MACs). Also on dlink you can define a port that is “transparent” i.e. STB connected to this port talks directly to ISP getting ip from it using teh MAC from the STB. As A result I have a lan within 192.168.1.0/24, dlink gets ip from ISP network 10.47.47.0/24 and STB also has ip from 10.47.47.0/24 network. STB’s ip is different from router’s IP

Now I have RB2011, optical cable from ISP plugged int sfp port. STP plugger to ether1. ether1 set as master for ether2,3,4,5. ether6 is the master for ether7,8,9,10. ether1 and ether6 are bridget as “lan”. There is dhcp client on sfp port, getting ip from 10.47.47.0 network and dhcp server on “lan” bridge.

Is there a way to repeat dlink functionality with routerboard?

Thanks in advance
