I need to find a way to prevent opnsense from assigning that autoconf EUI64 address on the WAN IF or else all IPv6 traffic originating from the firewall itself fails. By default the router is using 2604:5500:30c8:0:ae1f:6bff:fe83:22f7 instead of the DHCPv6 assigned address 2604:5500:30c8::662; all my LAN clients do get an IPv6 address via ...Gateways. Gateways define the possible routes that can be used to access other networks, such as the internet. All different paths that are available to your firewall can be managed from this page, which can be found at System->Gateways->Configuration. You can either define these gateways yourself, or they can be provided automatically from ...Note on IPv6: As of writing, CL still doesn't have native IPv6 widely deployed. Instead, they use 6rd gateways to provide IPv6 connectivity over IPv4. CL's 6rd gateways can perform poorly and cause decreased network performance and connectivity drops, so unless you specifically need to connect to IPv6-only hosts, I'd recommend that you disable IPv6 on …Unbound DNS ¶. Unbound DNS. Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards.

This doesn't cause a problem, but although I can disable the unused *_GW IPv6 gateway the status just gets stuck at "Pending ...For outgoing IPv6 access, you can usually allow any -> any, so the only question is incoming IPv6 traffic. When I do that, the devices on the guest-like VLAN will be able to reach the devices on the LAN VLAN without restriction. That entirely defeats the idea of allowing only what I want to allow. Quote.Jun 25, 2023 · Now go to Interfaces: [LAN] and set "IPv6 Configuration Type to "Static IPv6". Under the "Static IPv6 Configuration" block, set the IP address to ::1 and dropdown 128.

The root cause is a defect in some Intel logic ic's that deal with TCP and UDP checksum offloading with IPv6 packets, and turning off checksum offloading for incoming packets gets rid of the bug.All I did was get my IPV6 Global Address (usually ending ::1/64) from the Sky Hub Status page, set the OPNSense WAN port for my Sky connection to the same address +1 (so ::2/64) and then left it for about 15 minutes to sort its routing table out, after that gateway monitoring is fine and you can do ping/traceroute diagnostics from OPNSense and ...Because DNS servers are super reliable and never fail. It's a level 8 protocol (your brain) dependent on everything else. And you solve the issue on the lower level, the application one. The level 3 protocol works fine, it's just that you are not able to remember or process easily the IPv6 addresses.i have Opnsense in a DualStack Network. Inside this network there are some docker containers with IPv4 only, and i want to have HAProxy acting as a reverse proxy and as an "IPv6 offloader". I have configured IPv6 on the docker host and it can reach the internet via IPv6, so my Interface configuration in OPNsense seems to be correct.So eventually IPv6 starts to work on my opnsense box without any config change, probably waited for like 20-30 minutes maybe?
