[lime-dev] fd66:66:66:7:c693 IPv6 unaccessble but 2a00:1508:ac6:d000:: works ok

Hello, I’ve initially asked my question at https://github.com/libremesh/lime-sdk/issues/93 but have been redirected to this mailing list and I hopie this is the right place to ask. I'm trying to figure one thing out and can't wrap my head around it - maybe someone could help me with it. I create a small mesh network (2-7 devices) and it works fine initially. I connect with my PC to it and can ssh/ping and open LuCi over IPv4 and IPv6 addresses in IPv6 fd66:66:66:7:c693:ff: subnet (which is shown in LuCi under http://thisnode.info/cgi-bin/luci/status/bmx6/Nodes ) and 2a00:1508:ac6:d000:: (which is my option main_ipv6_address '2a00:1508:0a%N1:%N200::/64' in /etc/config/lime). After around an hour of working the fd66:66:66:7:c693:ff: address become's unavailable and only 2a00:1508:ac6:d000:: works. This only fixes after I reconnect to the Mesh Wifi network from my PC. I'm totally ok with using main_ipv6_address but LuCi bmx6/nodes shows only addresses from fd66:66:66:7:c693:ff: subnet which makes it very hard for end user to know what is the actual address of specific device (not to mention obtaining it's IPv4 address). Is there a way around this, eg. forcing Luci to show only the 2a00:1508:ac6:d000:: address or how to make fd66:66:66:7:c693:ff: not disappear after a while? For me this would be ideal scenario because figuring the IP address of each node is difficult - I understand how it’s calculated from MAC address but still looking for a single place which would list all the nodes addresses from 2a00:1508:ac6:d000:: subnet. I’m building the image from Lime-SDK commit https://github.com/libremesh/lime-sdk/commit/c3385846bf74d9b7530bc333f59fef… (because of https://github.com/libremesh/lime-sdk/issues/85) and with these packages: src-git base https://github.com/lede-project/source.git^01a8f0e444c9b52f100eff878cc7011f… src-git packages https://git.openwrt.org/feed/packages.git^1df38a4495a5eae7e39d10b93b3c7264a… src-git luci https://git.lede-project.org/project/luci.git;lede-17.01 src-git routing https://git.lede-project.org/feed/routing.git;lede-17.01 src-git telephony https://git.lede-project.org/feed/telephony.git;lede-17.01 src-git libremesh https://github.com/libremesh/lime-packages.git;17.06 src-git libremap https://github.com/libremap/libremap-agent-openwrt.git;master src-git limeui https://github.com/libremesh/lime-packages-ui.git;master + my own repo for app with a REST API Target is ar71xx/generic and profile is carambola2. I can repeat exactly the same for https://downloads.libremesh.org/dayboot_rely/17.06/targets/ar71xx/generic/c… when flashed with lede-17.01.2-lime-default-ar71xx-generic-carambola2-squashfs-sysupgrade.bin - just ping the 2a00:1508:ac6:d000:: and fd66:66:66:7:c693:ff: and after 30-60minutes the fd66:66:66:7:c693:ff: will become unavailable but 2a00:1508:ac6:d000:: will work just fine.
