reassign 923746 sysctl
thanks
Thank you, and apologies for the noise.
int0 is the LAN interface, on which dnsmasq serves both ipv4 and ipv6
requests for dns and dhcp.
he-ipv6 is the tunnel out to the world (via ext0).
You are correct that dnsmasq is correctly advertising the int0 mtu
rather than the he-ipv6 mtu.
The problem is that sysctl is not setting
/proc/sys/net/ipv6/conf/int0/mtu to 1280, despite the fact that this is
set explicitly in /etc/sysctl.conf
So I think I need to reassign this bug to sysctl

I expected Windows to receive the correct MTU size of 1280 as set in
/proc/sys/net/ipv6/conf/he-ipv6/mtu
interface=int0
dhcp-range=tag:int0,::1,constructor:int0,ra-names,24h
There seem to be two different interfaces here. It looks like dnsmasq
may be advertising on int0 with the MTU for int0, and I'm not clear
where he-ipv6 comes into the equation.
