  • Could a VLAN setup be causing my Network Issue?

    Hello,

    We have VLANS setup here in which I did not set them up. I don't have that kind of knowleadge. Anyway, I used to be able to not only ping to any computer on the .10 subnet, but print to the printer as well. Like for two months I cannot print to the printer in that subnet anymore and I don't know why. I've discovered I can ping 1 machine .72 so far but that's it. Also notice how the firewall goes in and out of the .9.3 switch. I have to believe this is not normal, but I don't this is the problem cause it's been like that ever since we've move to this building. I don't know why the network engineer did it that way but it works so he must have his reasons. Could it be a VLAN setting or switch issue?

    Please have a look at my attached diagram and see if you have an idea about what I can look at or do to fix this?

    I have attached as a jpg file.

    TIA

    Don't know what the firewall is but it may be working as your router on a stick or doing something like that anyway.
    For me the best place to start is that device, at least from that diagram. Can you not get onto it mate?

      I can, but what do I look for or how do I check.

        First thing I would do is back it up (not sure what device it is) and then reboot it.

        What are its route statements etc. Anything about the internal networks etc?
        cheers
