I have recently moved to an MR600 from the EE 4GEE device I've had for a number of years in the UK. The MR600 is really good and has better bandwidth than my earlier device ... but:
I have both IPV6 and IPV4 devices in the house and for many years have used the IPV4V6 setting on the 4GEE device. This gave me both IPV6 addressing and IPV4 addressing on most devices. For the MR600 it has three PDP settings: IPv4, IPv4 & IPv6 and IPv6:
- IPv4 gives me IPv4 connectivity but no IPv6 as expected.
- Likewise IPv6 gives me IPv6 but no IPv4 again as expected.
- However, IPv4 & IPv6 only gives me an IPv6 address for the connection. I don't get a corresponding IPv4 address and therefore my IPv4 only devices in the house and external websites that only support IPv4 cannot communicate beyond the house network - there is no gateway for them to communicate with and no functioning IPv4 dns on the MR600.
Given that I know this is possible - it's worked for years with my EE 4GEE device, I don't understand why the MR600 isn't supporting this dual stack approach properly. How do I report this as a bug? The EE 4G network is a full IPv6 network with a 464xlat implementation to enable dual stack.
