Ping is relative; it is simply the time it takes for a packet to transfer between the server and the client, that value you have stated is irrelevant.
The download speed is somewhat slow, however the upload (unlike previously stated) is actually considerably better than all ADSL lines generally offer; the way ADSL lines function, means that upload will always be slower than download. My speeds at home generally run at around 6mbs download and 0.2mbs upload and I can host generally fine for sandbox games (shooters sometimes lag a bit, but other than that it's fine).
You should post a picture of your port forwarding rule along with a picture of "ipconfig" into command prompt.
And just check you have set an exception up in your firewall.
