5G home internet and port forwarding

Hi, 

I need my 5G home modem to access two ports (8092 TCP and 1194UDP) for a device that is essential to my work. The Telstra support pages say to set up a static port, but this is not permitted with a 5G modem. 

Here is the Telstra support page on port forwarding: 

https://www.telstra.com.au/platinum-technical-support/articles/port-forwarding

 

When I go into mygateway and click the router tab for static rout it says "This function is disabled for Mobile WAN type". 

I rang the 5G support people and they said that they had no knowledge of such things and that this was my problem not theirs (most unhelpful!). 

 

Does anyone know how I can resolve this? Surely port forwarding is a common requirement. I am confused as to why Telstra would be selling a product that restricts use. 

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

Re: 5G home internet and port forwarding

I just found this unofficial manual, which is amazing: 

file:///Users/ellierennie/Dropbox/other%20stuff/Telstra_5G_Home_Modem_AW1000.pdf

 

It looks like I can configure port forwarding if I turn the mobile radio off. While this is not ideal, it means I can access my device if I am away for long periods. I won't be able to do it while at home and using the WiFi (at least that's my interpretation). Big shoutout to @cf4 for this - I am VERY grateful for your work!

Re: 5G home internet and port forwarding

Yes, it is a limitation of using a 5G connection at the moment (the implementation is not evolved enough yet, ideally you'd just have a unique IPv6 address for each device and then port forwarding is irrelevant).

 

You also can't bridge the modem in order to use a secondary router to enable the functionality.

 

@cf4 have you any ideas on what may work?

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

Re: 5G home internet and port forwarding

I dont think there's any workarounds for port forwarding to work

The IPV4 is CGNAT'ed and the IPv6, while public, has restrictions on incoming connections

Re: 5G home internet and port forwarding

I don't know of any workaround. As @Yastiandrie has stated port forwarding want work due to IPv4 carrier grade NAT and incoming connections on IPv6 being blocked by Telstra. In addition to this the modem firmware blocks port forwarding when in 5G mode. The only way I could access my cameras remotely when using modem was to install team viewer on a laptop which had to be constantly on and then remotely use the browser on the laptop to view the cameras. I would not recomend using this method as laptop has to be left on and with team viewer installed and running is a security risk.

 

@arggg Just to clarify that it is the 5G radio that has to be turned of not the WiFi radio. So unless modem is configured as router with its WAN port connected to an internet source will still not have remote access.

 

The information on the 5G home connection does state that servers are not supported. There is probably a reason why telstra blocks IPv6 incoming connections but due to this block I can't see how to make port forwarding work even if the modem allowed port forwarding when on 5G mode.
