wifi router TL-WR841N (TL), firmware 3.13.33 Build 130506, rel 48660n

I'm connecting the referenced devices in cascade in LAN to WAN connection, but I can not get internet on the router-wifi (TL) LAN.
The following is the procedure I tried:

1.- The WAN port of the TL was connected to a LAN por of the TD (modem-wifi).
2.- The IP LAN address of the TL if different of the IP LAN address of the TD
3.- Both devices has DHCP enabled,

The following are facts of the connection:

1.- There is internet acces at TD LAN
2.- There IS NOT internet access at TL LAN
3.- The TL get its IP address from TD from DHCP
4.- LAN to LAN cascading works fine, but I need to do access control on the TL-WR841N, which seems not to work on LAN to LAN connection

Please inform if the LAN-WAN connection is posibble with the referenced devices and in case of afimative answer, please comment what I'm missing or doing wrong

Thanks in advance for any comment.
