17.7 Legacy Series / running native IPv4/IPv6 dual stack
« on: September 13, 2017, 05:40:27 pm »
Hi,
I'm trying to run ipv4 and 6 on OPNsense 17.7.1_2-amd64 and although I can get ipv4 running fine (non-NAT) trying to get ipv6 working as well has been difficult. Additionally, there's no documentation for exactly what I want to do, though there is some for tunnelling with HE.
I have a an ipv6 /64 neighbour discovery range, a ipv6 /48 range for the LAN and and a /29 for ipv4. None of this is natted, all the connecting equipment have their own firewalls so the firewall is turned *off* in opnsense. re0 is WAN and re1 is LAN. pppoe0 is linked to WAN. The LAN interface is statically configured with a ipv4 IP. This works fine, on IPv4.
So, to configure dhcpdv6 I go into services > dhcpdv6 and it errors with the following:
"The DHCPv6 Server can only be enabled on interfaces configured with static IP addresses. Only interfaces configured with a static IP will be shown."
So I go into Interfaces > LAN. The static ipv4 IP is already in there. (and I'm not sure if I'm right here), select for ipv6 static ip, give it the /64 (and I'm also not sure if I should give it the /64 network, or just one IP in the /64, or even if it should be static) and try to save the change and it errors with:
"The following input errors were detected:
This IPv4 address is being used by another interface or VIP."
What should I do?
