Zywall 110 IPv6RD

Hi @mfriberg ,

Had you tried the steps that Zyxel_Charlie provided?

Then collect the packet on WAN interface to check if ISP has responded to the device.

Can you share your configuration on your IPV6 settings?

mfriberg

Yes i have tried resetting everything and start from new again

How do i collect the packet on WAN interface ?

My ISP info on IPV6rd configuration for my ip range

IPv4 BR adresse: 158.248.255.254

IPv4 Prefix: 17

IPv6 Prefix: 2A00:FD00:FFF4::

IPv6 Prefix Length: 47

IPv6 DNS: 2a01:798:0:8012::4

My Zywall does not give any IPV6 dns info ??

Side note:

I have changed ipv6 address/prefix length to 2A00:FD00:FFF4::1/64

and Advertised prefix table to 2A00:FD00:FFF4::/64

@DHSN, what part does not work for you ?

DNS via DHCP or IPV6 connection ?

Hi @mfriberg

Here is the example how to collect packet.

GO to Maintenance > Diagnostics > Packet Capture > Capture to select the Capture Interfaces > click Capture

After a while, click stop and go to Maintenance > Diagnostics > Packet Capture > Files > select the files and click Download to check the packet on WAN & LAN

Hi @DHSN

Hi @Zyxel_Jerry

After check the image you provide, the information is still not enough to know which part cause the client cannot reach the Internet access.

It need to step by step to figure out why the client cannot access to the internet.

First, check if the client can reach WAN interface and WAN gateway, use ping to check if client can reach them.

If the client can reach WAN interface and gateway, then go to check the second step,

Use device Network tool to check if the device can access the internet, ping dns.google with IPV6 type to check.

Below is the steps to check networking on the device.

Go to Maintenance > Diagnostics > Network Tool > select PING IPv6> fill in the dns.google > click Test

IPv4 or IPv6 ?

Hi @mfriberg

It means to check if the client IPv6 address can access to WAN interface and WAN gateway.
