23.7 Legacy Series / Multiple IPv6 IPs on WAN issues

« on: November 15, 2023, 08:49:56 pm »

Hi guys. I'm trying to understand with my VPS provider with isn't my IPv6 setup working properly.

I'm assigned 5 /64 IPv6, which one is the main one and the other 4 are like aliases. To configure this on OPNSense, I've configured one directly on the interface using Static IPv6 and defining a custom GW for it, the others are defined on the Virtual IPs setting.
The symptoms I'm observing is that only when I ping the IPv6 GW from any of the source IPv6 is that the traffic actually "works", as in, I can reach the internet via IPv6. After 10-20s of stopping the ping to the GW, all traffic stops (from either of the 5 IPv6s).

What am I missing on my configuration or what did I do wrong here?

22.7 Legacy Series / IPv6 connectivity woes

« on: December 03, 2022, 07:48:18 pm »

Hi guys!

I'm trying to setup IPv6 connectivity on the "lan" side of the opnsense firewall but for some reason, while i do get and IP, it doesn't talk to anyone.

Setup is like this:

Internet ----------- [WAN: SLAAC] OPNsense [LAN: Track Interface WAN] ---------- Clients

OPNSense has internet connection no problem.
Any client that connects on the LAN side of it, get's and IP address (2001:XXX) but can't use it for anything, not even pinging the LAN interface (that also get's an IPv6 address).

Nothing obvious shows up on the firewall logs.

Any ideia of what I might be doing wrong?

22.7 Legacy Series / 1:1 NAT for a Virtual IP (from the LAN side)

« on: August 05, 2022, 01:15:29 pm »

I have 2 Virtual IPs assigned to the WAN interface (plus the "normal" one), and I've created 2 1:1 BINAT rule for those and everything is working fine. What is not working fine is if one of the LAN hosts tries to talk to one of the VirtualIPs, the firewall, instead of forwarding the request back to the LAN to the designated host, just consumes the request for itself. Is there any configuration that I'm missing here?
