Short Version: I would greatly appreciate it if someone would create a plugin to allow SSDP broadcasts to be rebroadcast to all VLANS. (SSDP broadcasts are UDP packets sent to 18.104.22.168 on port 1900) Since 22.214.171.124 is a multicast address I cannot figure out a way to forward it across VLANS. I get the impression this would work to DLNA as well, but I have not confirmed) Much Longer Version: I recently got a Chromecast and want it to work on both my main home network and my guest network. For reference I am using Shibby's version of Tomato (Thank you Shibby's it is awesome!). I have two VLANS setup LAN (My primary network) x.x.a.0/24 and LAN1 (My Guest network) x.x.b.0/24. My Chromecast lives on the LAN VLAN and all devices there are working. However, it does not work at all on the guest network. I did a lot of Google research and network traces and as far as I can tell the Chromecast discovery process works as follows. Client device sends SSDP "discovery" request to 126.96.36.199 port 1900 Router broadcasts that request to all devices on the subnet Chromecast receives the broadcast and sends essentially a webpage redirect to the IP that sent the SSDP "Discovery" request Client and Chromecast carry on a fairly standard web browser/web server conversation on some odd ports (8008, 9080, etc) (Technically this process is DIAL http:/dial-multiscreen.org) Everything after the broadcast can be done on the LAN Access page (it is just standard IP to IP access), and I have set that up. However, the SSDP "discovery" broadcast has me completely stumped, I cannot find any way in the interface to forward SSDP discovery requests on LAN1 to LAN, much less doing so while keeping the source address unmodified. This leads me to believe that someone needs to write a plugin to accomplish this. Unfortunately, that is beyond my current abilities. Is anyone willing to do this for me, and anyone else who might be interested? If so, thank you very much in advance.
