    Hi everybody!
    I have a web server and i tried to be public using "Port Forwarding" of my new RV042, but it doesn´t work.

    The configuration of my router is the next:




    I have the RV042 Firmware v1.3.8.2 Release

    Please anyone tell me something because I became crazy.:confused::eek:

    Your ISP blocks incoming port 80 request at your modem. Cable or DSL. If DSL then your Modem is actually functioning as a router and is doing NAT between the 2 interfaces and would need a port forward added to it as well.

    Cable companies generally block incoming port 80 request to the modem.

    Try setting a UPnP forward from 8080 to your internal ip on port 80 then try you request from outside your network as http://ip_address:8080 and see how it goes.

    You only need either the Port forwarding entry or the UPnP entry but not both.

    Hi Venom51!

    Thanks for your reply.

    I'm sure my port 80 isn't blok, because i can do it with the BEFVP41.

    Is this possible to have this problem although if i have enable my modem (it's a router like you said) as a port DMZ.

    My configuration of the internet is the next:

    Internet ---> (Router ADSL) ---> RV042 ---> Web Server
    . (DMZ) (Port 80)

    Why are you using port forwarding and UPnP and port triggering? You only need port forwarding or UPnP but not both. And of course make sure that the RV is the default gateway for your web server.

    I have setup an RV082 with port forwarding 80-->


    I have to add an access rule (Under Firewall) that allows HTTP traffic from WAN1 to reach the address.

    I hope that helps.
