    Default Crossing LANs

    Ports 1&2 are WAN
    Port 3 PRIVATE LAN 192.168.1.x
    Port 4 PUBLIC LAN 10.1.10.x

    I have no PCs on the PUBLIC LAN. This is primarily the free wifi for customers. Until I figure out the Q See issue, I have the NVR on the PUBLIC LAN. My question is: is there a way to establish a rule that will allow a specific desktop on the PRIVATE LAN to cross LANs so I can access the NVR from it? The facility is a couple hours from me so I frequently connect to one of the desktops to troubleshoot. One issue is that this is also the PC that where the NIC won't stay in static IP mode.

    we kind of need to know what you did to block them. The 2 subnets should be routed.

    I didn't think machines couldn't talk across physical ports. This is with a u50w.

    By default all traffic passes, you have to configure something to block it. Or, far more commonly... goof up an IP configuration on a workstation so it cannot communicate.

    I definitely want the subnets to be separate. Well, except for what I'm asking in the OP. I did what is in the attached. Doses this mean I can access the public from the private?

    FYI. The above doesn't work. While trying to troubleshoot some hardware issues with support, I ended up on the 10.x subnet. I was able to connect to and log into the u50w. Not good.

    agreed.

    WARNING: Improperly configuring input filter rules can compromise the security and proper functioning of your Untangle server.
    WARNING: Disabling rules in the default configuration may interfere with the proper functioning of many features of Untangle.
    There are two rules not enabled by default:

    • Allow HTTPS on WANs - enable this rule if you would like HTTPS access externally.
    • Allow SSH - enable this rule if you would like SSH access to Untangle's SSH service.

    WARNING: Changing other settings is Input Filter Rules is not recommended.



    input filter rules aren't even what you want anyway

    I would not expect your rule to work as you have created an input filter rule there and what you need to achieve your goal is a forward filter rule. Please create this rule in the forward filter rules section and test again there. Thank you.

    Thanks. I was not connecting through the WAN. So how do I ensure traffic is blocked between LANs if it's not though input filters.
