It is wrong. You forwarded port 80 on protocol UDP. A web browser works on port 80 protocol TCP. Change it to TCP 80 and it should work.
I tried to do the Virtual server on my router.
QuoteI tried to do the Virtual server on my router. So what router do you have?
Many routers with Nat and port forwarding wont allow an external connection , if it appears to be coming frominside the LAN.So, to test that your port forwarding works, you have to test it from outside your lan.
To test from outside your LAN, you need to know your current router WAN IP address (see below), or use a dynamic IP service.http://checkip.dyndns.com/
Try using an external port different from TCP 80. Try, for example, TCP 81.Then, externally, you'll access your Arduino like this:http://<your.ext.ip.addr>:81Another thing: port forward may not be the only required step. It may also be necessary to explicitely open that port in the router's firewall settings, so your router can respond to requests made to it. Then it will forward request to that port from the external (WAN) clients to another port (or the same) in the internal LAN server.
