Hi

I've been using an Ubiquiti USG for about 6 months now and all is good with the IPv4 connection, but IPv6 is not working... Some of this appears related to the new controller version I'm running but I wonder if its also the mss-clamping setting.  Presently, with IPv6 set to DHCP-PD and IPv4 recieving the static IP, the MSS clamping is sitting at 1452 in the config when I run mca-ctrl -t dump-cfg on the USG itself.  I've read other posts that perhaps the MTU should be set higher, somewhere around 1508 and therefore the corresponding MSS-clamping setting would also be higher than 1452 (1480?).

Anyone else running a USG with 2degrees and IPv4/IPv6 running?  For reference, my controller version is 5.8.24 which might have broken IPv6 but I want to eliminate all other issues first.

Thanks,

Chris
