Hello,
I am asking for your help on ipv6 which was working but has now stopped.
If you have any ideas for testing as I suspect something is broken with my ISP doing a recent ipv6 deployment.
First of all the modem doesn't work like most of the setups I see on the forum.
We do not use PPPoe
The modem sends the identifiers over the network to the box.
We do not know our credentials.
The box cannot be in Bridge.
The only functionality is DMZ mode.
I am in IPV4 with Mikrotik and in DMZ, everything is OK.
I made the settings for IPV6 in DMZ as well and everything was OK, but for 7 days I have been tearing my hair out because the Internet link no longer works.
The IPV6 distribution on the devices is OK.
I can ping my machines locally but I can no longer go out on the internet.
From the Mikrotik RB4011 router I can ping google ipv6.
I am currently using the basic ipv6 filters from a reset of the router configuration but nothing better.
This is how the modem works (DMZ only)
BOX
I receive a fixed IP with a / 56 prefix
In the DMZ option I get a subnet / 64 with a gateway IP
SLAAC is activated on the box.
RB4011
In mikrotik I added an address like this: 2a02: xxxx: xxx: x302 :: 1/64
From there I could have an ipv6 address on my machines and go out to the internet.
The ipv6 test sites were OK on the fact that I am good at IPV6.
Today I can no longer ping the internet.
Windows indicates that there is no internet connection.
I don't see any ipv6 dhcp.
Can you give me help or search ?
this configuration is exactly the same when it was working.
Thank you
