Hello all. 
I have a problem and I would like that you were helping me.
Since one sees in the image I have 3 mikrotik and have to connect them of the following way:
R1 access to Internet
R2 connected with cable of network to have access to Internet and connecting for wlan he has to happen for the hotspot of R3 and go out to Internet.
Can you help me please?
That is something simple but I am new in this 
Graces, regards
I manage to give servicion to R1 and to enable the ETH2 with access to Internet to which I connect r2 which has to have a hotspot but with a tunnel towards the wlan of R3
Only he has to happen for the hotspot the people who connects to the Wireless of R3 the one that connects for cable ETH to R3 have to go out directly to Internet.
First DHCP client in ETH1 of R1 for cojer IP of Internet.
Second I assign an IP to ETH2 of R1 on which I believe a DHCP Server and do in IP/Fireware/NAT masquerade this IP.
With it at first with it lead to Internet to R2 connected in ETH2 of R1 I can can do the same thing with ETH3 for the R3 with which already I have service to Internet in all the MKT but now I have to enable the Wireless of R3 and create a Tunnel in order that only those who connect to Wireles Of R3 happen for the Hotspot of R2 and go out to Internet being validated.
thx
Regards
