MikroTik

i have a mikrotik 133 rb as an AP.with another 133c as a client and working very fine for now. iam using it for internet link btw two site of about 5km apart.i also have another mikortik os installed on a desktop computer. i want to use the desktop which is on a demo license at the AP instend of the windows machine iam using. my problem here is that i can not ping the client from the desktop.i tried using another windows machine. the internet connection is at the client site.i can browse at the AP but i cannot ping the client.
i really need assistant here so that i cant try the mt machine

make sure your ip has been routed. and make sure firewall is not configured on your machine.
try to use traceroute tool for tracing problem

thanks,

are you using the hotspot feature? try and "MAC ping" from within Mikrotik. If that works and normal ping doesnt, Id guess a firewall issue.
