Hi all. I have news that is my own experience. From early days of bits I have been running all of my wallets with internet connection that is behind Internet Provider NAT. Under these connections, usually 3G and 4G mobile connections you dont get direct connections by opening modems NAT rouling from its configuration page ie. 192.168.1.1 or something else.

Well over month ago I got normal ADSL connection with public ip and now I am able to open NAT ports to all my wallets and now I am having more connections to network than ever. For Bitstar now 9 connections and its usually over 12 to 14 connections. Before this change I had 3 connections.  By opening Nat you can also download blockchain faster.

I hope this helps.
