We are using IPv6 4G router for our project and bought almost 14 units of Archer MR600

6 Units of (HW: Archer MR600 v1)

8 Units of (HW: Archer MR600 v2)

Total 14.

Our project is primarily using IPv6. The Simcard & APN are private from the Telecom provider and have static IPv6 address.

Our aim is to host some small server on PC connected to MR600 on IPv6.

Initially, we tested the modem on Ipv4 using the DMZ option where we can put the local IP of PC, so all the traffic can be forwarded to the PC.

This works perfectly and all incoming connections are received at PC and served.

But when we wanted to do the same on IPv6, we cannot do it. Actually, we don't see the space to write local pc IPv6 address because DMZ has only 4 boxes for IPv4 address.

We are able to initiate a TCP connection from the PC to the remote device in the same network on the IPv6 apn but the other way around does not work. I.e When the remote device tries to connect to the Local PC the MR600 does not forward the connection to the PC. While the same things work perfectly on IPv4.

We tried this on both Hardware  Archer MR600 v1 & v2 but it did not work on both.

I will appreciate your precious advice as we have already had many units but we cannot run the system.

Thanks
