setting up a hotspot guest login separated from LAN

Hi all,
sorry for the rookie questions, it´s the first time configuring/using that. My purpose: setting up a hotspot guest login separated from LAN on a RB751G-2HnD on v5.23

I get a DHCP IP on my client, i can log in, but always have time outs no response whatsoever, from the boards terminal, i can ns lookup, but nothing comes back from the internet. Can please someone help, i am sure it´s a dumm rookie mistake, here some exports:

/ip route
add disabled=no distance=1 dst-address=0.0.0.0/0 gateway=192.168.0.1 scope=30
target-scope=10

/ip firewall export

/ip firewall service-port
set ftp disabled=no ports=21
set tftp disabled=no ports=69
set irc disabled=no ports=6667
set h323 disabled=no
set sip disabled=no ports=5060,5061 sip-direct-media=yes
set pptp disabled=no

Do you need more exports, better which one do you need?
Thanks in advance to every suggestion!!
