    I have 2 RV082 units set on two subnets, the reason for the split is security, however the problem I am running into is odd.

    The setup:

    DHCP enabled
    Set in gateway mode as it acts as the gw for both subnets
    static route set to 192.168.2.x with a gw of the staic IP of the second unit

    192.168.2.x connected to LAN port of #1
    DHCP off
    Set in router mode
    static route set to 192.168.1.x with gw of the IP address assigned to the #2 unit.

    I can ping across the subnets but I can not browse by IP nor map a drive. I have tried every port I can think of and even set a test box as DMZ, but as long as the firewall is on in the #2 box the traffic is blocked regardless of the rules. If I turn off the firewall in the #2 box I can browse and map fine.

    Again the main reason we are set up this way is for complete control and denial of net access and various ports on subnet number two so just plugging into the lan side of number 2 is not an option for us.

    I think I have been looking at it way to long as I am out of ideas.

    Any assistance anyone can provide would be excellent!

    Thanks in advance!

    I havent played much with the router function of these soho routers so i do not know for sure how they act, but i do know from reading that they do funny things. Having looked at the settings however, it appears in router mode they want to talk routing via routing protocol. You have one router talking rip most likely and the other not doing anything, i would think that perhaps it may have issues. I have no idea why the firewall functions the way you describe in router mode, mayhaps someone will have a reason for that. However you can do what you describe and have port forwarding work how you want by putting #2 in gateway mode and make sure you plug the wan port of #2 to the lan port of #1. Yes you will be double nat'd but the network will work the way you want it too.

    Couldn't have explained it any better myself :)
