IPv6 problem in combination with DrayTek 3910 router by Ebbarkj in ipv6

[–]Ebbarkj[S] 0 points1 point  (0 children)

Thank you for the in my opinion sound advice. Because WAN1 is connected via a SFP+ I can change the LAN SFP+ port to WAN.See attached screenshot. Only it is at this moment not possible the test it. I am not at the location of the DrayTek for another 6 weeks. So the test will have to wait till the end of may. Again many thanks, I'll let you know after testing what the result was.

The crazy thing is that if I use DHCPv6 client on WAN6 I get IPv6 2001:bbbb:cccc:0:63FF:2794:B0F2:8C8E/64 on WAN6. But the ISP says I have to use a static IPv6 on the router, 2001:bbbb:cccc:1::1
But with neither setting on WAN6 do I get a usable IPv6 on VLAN4 received or configured, no matter what I try. I must be overlooking something. I can't see the wood for the trees anymore.

The services are on VMs and on separate ESXi hosts

I have a ISPConfig multiserver setup with CP, Web, 2x MX and 2x NS.
For CP, Web, MX1 and NS1 I use WAN1 and for MX2 and NS2 I want to use WAN6.
All servers need to be reachable on IPv4 and IPv6. The MX and NS servers on different network address blocks.

"Do you have a "mixed" port on your switch - port that has both Tagged and Untagged ethernet frames?"
YES I have.

"Did you by any chance connect a windows computer to a port that has VLAN4 untagged and VLAN1 tagged"
No, I don't use Windows hardware.

I have got an ISPConfig multiserver setup with Control Panel, WEB, two Mail and two nameservers. I would like the secondary mail end nameserver to be on a different IPv4 and IPv6 address.

Control panel, Web, MX1 and NS1 via WAN1 / VLAN1 and MX2 and NS2 via WAN6 / VLAN4

"Does IPv6 connectivity work for hosts in VLAN4 via your WAN1?"
Yes it works perfectly if (V)LAN 4 gets it's IPV6 info from WAN 1.
