Hi all.
I have looked up some articles on getting ipv6 on the second router. However so far I have not been successful. I was wondering if someone would be able to help point me in the correct direction.

Xfinity cable modem (cable modem only - no router)

Gateway/primary Router: Linksys MR7350 DDWRT DD-WRT v3.0-r60771 std (04/26/25)
Prefix Delegation /60, dnsmasq used for ipv6 RA (I know not up to date - the router is stable and receiving ipv6 and also handing out to LAN clients perfectly. Leaving alone for the time being)

Second Router: Linksys MR5500 Running openwrt snapshot with LUCI.
openwrt seems more stable than DDWRT on the MR5500 at this time.
Currently also set to gateway. Pretty much stock openwrt settings. I am more familiar with DDWRT, but not much beyond the basics.

Connection
Cable Modem -> DDWRT router LAN -> openwrt WAN

Both networks have different subnet
192.168.A.x and 192.168.B.x

I do not want these routers on the same network

I would like figure out how to get IPv6 on the second, openwrt router. Bridge? Pass through?

Intention: Main DDWRT router - keep as gateway. second openwrt router as a dedicated either onion router or openvpn/wireshark router with my vpn.

Any help is appreciated - if what i want to do is achievable. I assume I will be making some adjustment.

Thank You

You should consider asking on the OpenWRT forum, but for the sake of whether or not you even looked this up or read this page:

https://openwrt.org/docs/guide-user/network/ipv6/configuration

Anyone who chooses to help may do so, but this is not the OpenWRT forum.
