NUC running OPNsense 24.7 can't see WAN interface from Adtran 422G GFast NTU

DSeven,

Well, I got there in the end - with much thanks to you and Patrick M. Hausen.

One minor issue though is getting the DHCPv6 server under the services to run.  Any thoughts as to what might be causing this, and when it comes to letting people through to access my Plex server, I'm assuming that I do this under the Firewall/NAT/Port Forward menu item?

Again, please accept my thanks here for all that you done to help - very much appreciated indeed!!! 😜

Glad you're making progress!

For IPv6, you may need to find out what your ISP provides. As a guess, you could try configuring your WAN interface "IPv6 Configuration Type" to DHCPv6, and under "DHCPv6 client configuration" (further down on the same page), check "Use IPv4 connectivity", then look under Interfaces -> Overview, Magnifier next to WAN and see if you see "Dynamic IPv6 prefix received"? Failing that, ask your ISP if they are delegating an IPv6 prefix to you, and how....

Thank you for that - will take me a bit to look into this.

One thing that I do note has happened is that my shared drives no longer seem to work.  I have two PC's.  One is my main rig while the other is a Plex Server.  I was previously able to see and access the drives of each PC from the other PC, but now this is not working.  Do I need to do something in OPNsense to get this working - and, how do I assign an IP address to a specific MAC address?  These as well as being able to do port forwarding which I think I know how are the only things left for me to work out at the moment.

I did see an article that I thought might help regarding accessing drives from different PCs (https://www.thomas-krenn.com/en/wiki/OPNsense_add_interface#:~:text=Select%20the%20desired%20network%20interface%20under%20Interfaces%20%E2%80%A3,the%20desired%20IP%20configuration.%20Click%20on%20Apply%20changes.), but this didn't seem to do the trick - at least, I couldn't work it out from what the person said.

If the two PCs are on the (same) LAN, OPNsense wouldn't be involved in communication between them. My guess is that Windows might think that you've moved onto a public network, and it blocks sharing on public networks. Maybe something like https://learn.microsoft.com/en-us/answers/questions/73866/how-to-change-network-settings-from-public-to-priv

You can use use reservations to have DHCP assign fixed IP addresses to known MAC addresses, but note that those IP addresses must be outside the general address pool: https://docs.opnsense.org/manual/dhcp.html#reservations

Got the PC thing sorted out, and it wasn't the OPNsense.

One issue I am having though is when I download stuff (torrents) using VPN Express as my VPN client and Vuze to download the material, my OPNsense box crashes within a few minutes - or should I say, I can no longer ping the OPNsense box from any PC on the LAN.  I've restarted all networking devices (the 2 x WAPs), and everything is still down.  Once I restart the OPNsense box, everything comes back up.  Any thoughts on this?!?  🤔
