    I need to establish a VPN tunnel between two RV042s. One of them is behind a NAT router provided by the ISP. How could I accomplish this? By forwarding specific ports?

    Sure, I'd be happy to help.

    First, make sure your DSL or Cable modems are set to allow VPN pass-through.
    Second, if your DSL or Cable modems have a DMZ setting, set the IP address to your Linksys router.
    RV042-to-RV042 or BEFVP41-to-BEFVP41 will work behind your NAT enabled DSL or Cable modems.
    RV042 to BEFVP41 will NOT.
    RV042-to-RV042, one must be set to aggressive mode.
    BEFVP41-to-BEFVP41, do not require any special settings, they just work.
    Use two different subnets, one for each network.
    Example: on the first network, on the second network. VPN will automatically take care of all the routing.

    Use static IP addresses on all your workstations. This is NOT required, but it will help you keep your sanity. If you do this, add entries to your HOSTS file. Dick Jane Jack Frost
    or always use the IP address when trying to connect to remote pc's.
    Example \\\Share instead of \\Dick\Share

    Even better!! If you are running a file server and install the WINS service, set all workstations WINS setting. This is totally slick.web directory submitter
