Deny LAN access, Allow WAN access

    I have not found anything like this on the forum, but maybe my search terms are wrong.

    Is it possible to isolate 1 computer within a LAN and deny all LAN access and only allow internet access? I have a RV042 w/ newest Linksys firmware.

    A VLAN setting for that computer could do that, but I don't believe the RV042 has that function (or at least not a documented functionality).

    The RV042 has undocumented QoS capabilities: The VLAN functionality of the RV082 is on the same port management page that has its QoS settings so perhaps the RV042 has VLAN capabilities in there someplace.

    Thank you.

    I see the QoS stuff there but not VLAN.

    How many clients are running on your network?

    As an alternative, you could restrict access by a client firewall such as Norton Personal Firewall (or Norton Internet Security) which can block access from certain IP on the network, but you'll need to install one on each computer that you wish to block access to.

    I have 11 clients on this LAN. It's a complicated LAN to explain so avoided it.
    There is a wireless bridge going to one location then a CAT5 from this location to an employee's residence that they want to isolate from LAN.

    I came up with a simple solution, and now feel stupid.

    The wireless bridge comes into a WAP54G. Will use a WRT54G in bridge/router mode to relay. CAT 5 from LAN port on WRT54G to Internet port on a BEFSX41, then LAN port to the isolated computer.

    Thanks for the brain time.
