[Feature request] radvd multiple subnets

[deasmi]

I've recently made the switch from pfsense for 'reasons'.

This has in the main been a smooth process, running on a PCEngines APU2.

One small thing I'm missing is the ability to have multiple subnets advertised by radvd, but it is minor as I've just got my raspberry pi to advertise the second one.

Reason I do this is I have a HE.net for internet access, but as this could change, and hopefully will when Virgin media finally enable ipv6, I also use a block in fc00::/7 for local permanent addresses.

It would be nice if opnsense supported this as pfsense did.

Other than that I'm enjoying the interface a lot more and appreciate the ability to run libressl.

Apologies if this is the wrong area to post this.

Hi there,

Is that with a static IPv6 or tracked via HE gif tunnel?


Cheers,

PS: I'm asking because the router advertisements support multiple route segments, but only in static mode.

I get a /48 from HE.net, and pass the first /64 through to the LAN, I do use some of the others for VPN, Lab network.

I then have a /64 from the fc00::/7 block for internal use.

To be honest if opnsense can't support this, I realise not a normal use case, I'm not going to loose too much sleep as I'm just advertising the fc00::/7 block from my raspberry pi at the moment and that is working fine.

I would like to add my vote to this feature request.

I am in the process of moving from pfSense to OPNSense, and - like deasmi - would like the RA to anounce both a GUA prefix (the one I get from my provider) and a ULA prefix (one I randomly "generated").

Over at pfSense this was possible.
On the RA tab where OPNSense has the 'Advertise Routes' box, over there they have a box called "RA subnets" which announced additional prefixes/subnets.


I am using Track Interface (WAN) to get my GUA prefix.


The reason I would like this feature added is because I want to use ULA addresses internally.
At home I do not have a permanent prefix.
At work I do have a permanent prefix, but this will probably change at least twice in the foreseeable future (we will first move buildings, then later switch ISPs when fiber becomes available there)

That would mean I cannot count on my GUA addresses as being permanent, and I would very much like to avoid reconfiguring the network.

Having both subnets announced would be helpful in my case I think
