I have tl-mr3020 with openwrt 14.07 and configured wifidog to authpuppy server. I get error message page, when enable Policy to limit time duration. I found this errors in logs
iptables: No chain/target/match by that name.
[3][Thu Jul 27 17:00:45 2017][4433](fw_iptables.c:118) iptables command failed(1): iptables -t mangle -D WiFiDog_br-wln_Outgoing -s 192.168.1.133 -m mac --mac-source 10:68:3f:f9:ee:76 -j MARK --set-mark 0
iptables: Bad rule (does a matching rule exist in that chain?).
[3][Thu Jul 27 17:00:45 2017][4433](fw_iptables.c:118) iptables command failed(1): iptables -t mangle -D WiFiDog_br-wln_Incoming -d 192.168.1.133 -j ACCEPT
I have tried to add new chain manual, but got
root@OpenWrt:~# iptables -t mangle -N WiFiDog_br-wln_Outgoing
iptables: Chain already exists.
root@OpenWrt:~# iptables -L -n -v | grep Out
root@OpenWrt:~#
nothing
What can I do to resolve this trubble?
