Hi,

I would like to check if any of you guys have experience to port forward any network port via Digi's 4G network? I tried to port forward the network port servicing for CCTV as well as RDP service but the attempt was unsuccessful. Does anyone know if port forwarding is disabled by telco side?

Thanks.

I am currently using streamy 4mbps as my home broadband but the upload speed is too slow to for remote viewing. I am interested in the Digi infinite package to potentially replace my streamyx but before doing so, I get a prepaid and try out. But it turns out that whatever forwarded to the 4G router is not going out and I can't access it via the ddns hostname.

So I am not sure whether it is the limitation of the 4G router or Digi is the one blocking any ability to port forward to its network.

well I know 'double NAT' with the typical home network configuration. I have added my router to the DMZ zone in my modem and it works when the router connects to the TM's modem. But when i swap the modem to 4G modem and also include the router into the 4G modem's DMZ zone, it doesn't work though.

unless you are saying the ip address i get from Digi is not public ip.

Ah shag, there isn't any way to port forward with cellular broadband as backbone?

Well not until the charges of its package reach my comfortable level... Maxis data plan is expensive.

In this case, all traffic will be going through a third party right? VPN provider has to be trustworthy then?

I encountered network attack once, just because I did not set up the DDNS properly and hence my router was bricked. So I am quite sensitive to anything that might be going through a third party intermediary.

Is the setup going through an intermediate service/server? My setup is a typical peer to peer connection by exposing services to public internet.
