Hi everybody!
I build custom openwrt firmware for my D-Link dir-320 with coova-chilli, openvpn and webif-iw-lua-coovachilli (webif-iw-lua-pepperspot) frin svn.
I configure my openvpn client and coova-chilli, but when I try to open browser and want to see coova page, redirect is broken.
My /etc/config/chillispot file:
