port forwarding on FVS336gv3

I migrated from a sonicwall to Netgear FVS336Gv3, I´m configuring port fordwarding to permit RDP (in a special port 3839) and NAS (8080). I created a Service for each port, then created a service ...

Have you checked the network settings of the client? Check especially default gateway but also things like firewall. An incorrect set default gateway = works locally but not from Internet.

You can also run wireshark on the client to make sure traffic hits it. The log indicates that the message is being forwarded, the fact that port testers show it as offline means that nothing responds on that port. Which is likely to be an issue on the client rather than he firewall. Packet captures would be able to prove this; do a LAN packet capture on the fvs336gv3 from the diagnostics page, if you see the traffic go out the LAN but nothing coming back the issue is with the client or something in between.

Hello opeinado,

Welcome to the community!

Can you send me a PM of the screenshots of the Inbound Rules table and the rule itself?

Thanks,

Hi opeinado,

Kindly test if both ports 3839 and 8080 are really open on your FVS336Gv3 by using an online port checker tool like http://www.subnetonline.com/pages/network-tools/online-port-scanner.php. Fill-up the required fields then click "Scan Port." Let us know the results.

Regards,

DaneA

  Hello,
  
  I try with this applications. Both ports are offline/unreachable:
  The checked port (3839, service amx-rms) is offline/unreachable
  The checked port (8080, service webcache) is offline/unreachable

    Hi opeinado,
    
    I believe there is a modem connected to the WAN port of your FVS336Gv3. Is that modem a modem-only device or a combination of modem-router? If ever the modem is a combination of modem-router, you will need to configure port forwarding on it then check again if the ports will now be online/reachable using the online port checker tool.
