CG3000v2 Port forwarding Issue

Hi,

 

I've got a CG3000V2 from Optus around a year ago running firmware 2.07.05. I have issues getting port forwading to stay within the configuration. Scenario is as follow:

 

  1. Port forwading is setup
  2. Port forwarding works
  3. Router is rebooted due to hanging or internet disconnection
  4. Port forwarding no longer works
  5. Check port forwarding config in router. Configuration is still present.
  6. Remove port forwading and re-apply configuration
  7. Port forwading works.
  8. Repeat from 3

Any ideas on what might be causing this? Looks like a firmware bug.

      Hello Ujay62

       

      To port forward on this device log into the router by going to 192.168.0.1 in your web browser should get a box asking for a log in. You want to use admin/password for the log in and then click on firewall settings on the left side. Then you want to enter the ports you want to open in the add a custom Rules area then click add.

        defining a rule is not an issue. The rules stop working work after power failures and now even without any power failure. The rule will still be there when the modem comes back online after a power failure but trying to connect to the port fails (timout). In the past (until last week), I just changed the port to some other port and then it would work again but now even that does not work. What can I do to troubleshoot this issue?

         

        Thanks for your help.

        Gaetano.

    I'm having this exact issue as well. I've even tried to put the 3000 into bridge mode so I can use a second router for port  forwarding but that fails  as well. I think optus do something strange but calls to them results in 'this is an unsupported advance function, try netgear '.

     

    Tried netgear but gave up after 75 mins holding for a tech.....

    Hello quak58

     

    Have you tried a factory reset to see if this persists after you set up your port forwarding up again.
