Tomato firmware and LG 42lh50 HDTV

    Hello,

    I have tomato 1.25 Victek (non-ND) on a wrt54gv2 router set up as the main router connected to our cable modem. We have another wr850g router with tomato 1.22 Victek set up as a wireless AP/switch. We have multiple winxp computers on our home network that have been sharing files/folders between each other over these 2 routers for years.

    Recently, I bought a brand new LG 42" HDTV (model 42lh50), which has an ethernet jack in the back and can use CIFS to stream media (movies, pictures, mp3s, etc.) from the home network. But, when I connect the tv to either of the two routers, it does not see any of the computers on the network.

    This feature works great when I use another WRT54G v2 with stock linksys firmware. I connected the tv to that router along with one of our computers, and the tv could see the computer and all the folders it was sharing. Streaming movies worked great. I also have a dd-wrt router, which I could not get working for awhile until I disabled the SPI firewall as indicated in the following post:

    I have yet to get the tv to see any computers when connected to either of my tomato routers. I figured tomato must be running a similar (or the same) firewall, but I cannot find a way to disable it. I really want to use tomato as it has better performance than dd-wrt, but I am stumped on how to make this work. Any ideas?

    U can disable firewall by editting /etc/iptables on your`s router with tomato. One thing that you need is know what you want from iptables. Good Luck.

    I see that the main WRT54Gv2 is connected to a cable modem but can't tell how the WR850G, & other WRT54Gv2 connect to the main WRT54Gv2, if at all. I mean, I assume they are connected, with a cable, WDS, client bridge, etc. Might be in your description, I'm just not seeing it.

    Here is my issue. I have absolutely no idea what my TV is doing that is different from what my winxp computers are doing that would cause the firewall to block packets from the tv. I do know that the other stuff on the tv work great. It has the ability to access youtube, yahoo widgets, vudu, netflix, and it has an ip and all that good stuff. The sharing over the home network is the only thing that is having an issue. Is there perhaps a way to wipe out all the iptables entries and save it so that they stay deleted upon reboot?


    You are correct, the main WRT54gv2 is connected to the cable modem. The WR850G has DHCP disabled and is being used as a switch that is connected to the main router by one of its LAN ports. Both of these routers have tomato. I can connect the HDTV to either tomato router and get internet, but cannot view shared folders on the network.

    The dd-wrt and other wrt54gv2 are just spares i am using to test different stuff out and solve this problem. So far, I have managed to get the dd-wrt router working when i take the router by itself and connect it to the tv and one compuer. I got the other wrt54g2 with stock firmware to work the same way.

    What's your NAT Loopback setting under the firewall on the main router? Seems like that was related to file sharing issues, seems like either "all" or "forwarded only" setting was right, honestly can't recall at the moment.

    By default, tomato has it set to fowarded only. I have tried both "forwarded only" and "all," but it's a no go.

    Does anyone have any other ideas? I am seriously stumped here.

    Some sort of IP address conflict? Trying to think how that might happen but not much coming to mind. Most obvious would be, of course, conflicting static IPs or a static within the DHCP pool. I know it's a bit of a reach, just trying to think of possibilities.

    I made sure there were no conflicting ips. I think the iptables is the best bet for finding the problem. I just have no idea how to figure out which rule is the culprit. Or, perhaps the tv is doing something it's not supposed to.
