Telstra Smart modem Gen 2 - Technicolor DJA0231 - Firewall rules

Hi,

As there is no manual for this modem from Telstra, which surprises me... ( nor any un-official on I have been able to find ). Normal Telstra support level cannot advise on the below, and their "Platinum" group wants to be paid before...

 

For the "user-defined" firewall rules, does anyone have any details on what keywords, and or range words can be used for IP, and ports ?

 

For instance my "old" Billion modems manual states word like "any" can be used for IP and Port numbers, for port numbers a single number can be used or a range e.g. 1000-1050 

 

Can this be done for this modem/firewall ?

 

Thanks in advance

If you tap on the question mark top right there is online help.
If trying to port forward better to use the port forwarding settings at basic / services / port forwarding.

Hi and Thanks cf4,
Yes tried the ?-mark, but it doesn't provide that detail.

Not using port forward at this time, just want to lock down the perimeter, to minimum open ports

Leave IP address blank for any source or destination IP.
For a range of ports separate with : example for ports 83 to 90 use 83:90

I have the exact same problem. I can't get port forwarding working on my new Technicolor DJA0231 (Telstra Smart modem Gen 2). I've tried setting it both under WAN Services and under Firewall but it doesn't work. The ports are responding correctly internally on the network but is blocked from external ip's. Any idea on what todo?

I did but it didn’t work. Could it be that I’m still on LTE? My nbn is not connected yet?

Yes port forwarding will not work when on 4G backup as the modem does not have a public IP address due to carrier grade NAT.

Hello cf4,

You have answered a question in relation to NAT Type issues. So due to being connected on 4G backup while waiting on my NBN to be connected is why the PS4 is showing NAT Type 3 and along the port forwarding will not operate until the NBN is connected. Please correct me if I have it wrong?

Thank you.

Yes PS3 will show NAT type 3 as  when on 4G backup the modems WAN address is not a public IP address.

Hello cf4,

Thank you. That explains why even I was doing the correct process in setting post forwarding and setting an static IP address to the playstation, all this still gave me an NAT Type 3 message. Due to the 4GB backup. At least that is good to know when we are on NBN this should refer the playstation to an NAT Type 2 settings. Thank you again.
