Hi I recently switched over to OpenWRT 19.07.0-rc2 from Tomato. In Tomato web interface there's a way to limit the DHCP address range. I cannot find anything similar in the LuCI web interface. I have various addresses in Virtual Machines that are statically assigned and I don't want the DHCP server giving out those addresses, so I need to limit the range to .100 - .149 if it does not do that already.
Also I want to disable IPv6. I found directions in this forum several days ago that suggested:
cat >> /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.lo.disable_ipv6=1
However despite that I still have a WAN6 with an IPv6 address and I am seeing these two DHCP errors continually in the log:
Sat Nov 30 16:23:53 2019 daemon.err odhcpd: Failed to send to ff02::1%lan@br-lan (Permission denied) Sat Nov 30 16:25:26 2019 daemon.err odhcp6c: Failed to send DHCPV6 message to ff02::1:2 (Permission denied)
Short of creating a special build with IPv6 disabled how can I shut it off? Thanks
