Not working on v17

[luandro]

Tested on WDR-4300 and WDR-3500 using LiMe 17.06 DaybootRely (17.06 rev. ac18095 20180306_2236 and rev. 704029c 20181010_2325).

Installed ipset, ip6tables-mod-nat and uhttpd-mod-lua, copied all files using build-router.sh script and ran captive-portal start.

Expected behavior is to leave local traffic and redirect al other to portal. Actual behavior it blocks ssh and ping and doesn't redirect to portal. Tried stopping firewall, but it made internet traffic stop even after captive-portal stop.
