ZyXEL XGS19xx IPv6
Ally Member
We had some strange behaviour through VLAN's. It appeared that there was on 1 VLAN an IPv6 DNS Server on an old domain controller, and in default VLAN 1 the clients sometimes got this IPv6 DNS Server. But I also saw some IPv6 gateways.
When I surfed to those gateways I expected to get the firewall, but it was the management interface of the ZyXEL XGS1930-52HP(Which I moved to a different VLAN so cliënts wouldn't be able to access it, but seems only on IPv4…)
But at another client, we have some brand new XGS1935-52HP switches and it seems that the IPv6 stack by default is turned off. Is this a firmware change? Were there complaints about it in the past. I don't get why IPv6 is turned on in the first place on XGS1930 series, not good for security.
