I would like to connect to yun using IDE via internet connection
Hicheck the configuration of your router... some routers have a "DMZ" zone but placing a host in that zone is not enough: you must also configure the correct port forwarding and firewall rules to let the incoming packets (to port 22 = SSH) be routed to the host.
yes it seems ok... and the local firewall running on Linino can't be the problem if you're able to connect to SSH when in LAN.mmm are you sure the DynDNS record is updated? Could you try to connect using the public IP of your connection instead of the dynamic DNS record?
mmm probably we're missing something at the router level... try to disable the DMZ feature and leave only the virtual server config...
