Port forwarding/route preserving...

    Have a strange symptom. Seems to be something about the routing of devices in Tomato with my Linksys E3000.

    I have a networked Canon printer. IP address assigned and reserved. It has a memory card slot. The memory card slot is accessible via the network after mapping it. I've set that up before and used it.

    I've added an AIOS HD Media Player. Nice unit. When I do the network shortcuts in the AIOS for 2 NAS's drives, assign the correct IP's, etc., IP's for the NAS's reserved as well, AND have the memory card slot enabled in the printer, the AIOS when selecting the network shortcut goes to the memory card slot on the printer.

    If I disable the memory card slot, all IP's the same, etc., the AIOS works perfectly, I select the short the shortcuts in the AIOS GUI, the AIOS goes to the networked NAS's.

    The printer's memory card slot used the IP of the printer and TCP/UDP ports. I think they're 137,138 and 139.

    AIOS support says it something about the way the router is routing the destination information from the AIOS request to "see" the NAS drives.

    Never had this before but do I need to put in additional information for ports/etc. for the printer? If so, how?

    Is this a symptom of a RIPV1 or V2 setting? I had my setting to both being on and set to WAN.

    No ideas?

    Something in the router is blocking the printer and the memory card and so the router is confused.

    I reinstalled the printer software, reconfigured network settings, etc. and now I can not use the printer's ability to map the memory card slot. The "find the memory card slot" utility can't find the open port. This used to work. Since the it used to work time and now I've updated the router, messed with settings, etc., so many times i can't walk back to the time it used to work.

    Something is blocking the communication. Firewall disabled in Windows so it isn't that.

    I can print to the printer via the network. I can scan images from the all in one's scanner from the printer back to a network client. Just can't map the memory card slot.

    I have made progress. I reset the firmware in the printer and set everything to defaults and redid settings. The network now finds the memory slot and maps it correctly.

    I started digging into the problem due to my media server getting confused IF I enabled the memory card slot. If I enable the memory card slot for the networked printer when I tell my media server to go to one of the NAS devices, the media server instead goes to the memory card slot. IP's totally different, etc. Driving me nuts.

    In the media server's shortcut I went to details and in details was able to add hostname and domain names. I put in the domain/host names that I have in the router's Identification tab. The shortcuts in the media server now work. Goes to the NAS attached devices and not the memory slot.

    So what is that telling me?

    Problem with DNSMasq? Something is resolving the domain/host names properly without being manually configured in the shortcuts.

    DNSMasq disabled by turning off Use Internal DNS.... everything works without putting domain/host name in media player shortcuts.

    Still working on sorting this out. Help would be appreciated.

    In my media server if I create a network shortcut using just the ip address of NAS devices when I choose those shortcuts the router directs the request most often to my Canon printer's memory card slot. Not always but most often. If I put the NAS device name in the shortcut's "Host" name field, the shortcut works correctly each and every time.

    The router in order to direct the media server request to connect to the NAS device needs the names of the NAS devices as well as the IP addresses. I've read about some issues periodically with dnsmasq having issues with host names. Is this what is happening? DNSMasq having host name resolution issues?

    I also don't understand why turning off the memory card slot in the network attached printer stops the symptom. Other than the ports the slot uses I have found little information on how it makes itself "known" on the network. The memory card slot when enabled uses upd/tcp ports 137/138/139. I do not have port forwarding enabled for the printer. Not sure how I would do that either.

    ARP binding, dhcp assigned IP's, etc., all do nothing to address this symptom.
