Use Dos Protection: allow
Max Tcp Open Handshaking Count: 100
Max ICMP Count: 100
Max Host Count: 30
This can slow down your P2P programs like utorrent or Frostwire, since they are mistaken as attacks because so many connections are being made. So unless you are getting DoSed, disable DoS protection.
Otherwise your Firewall settings are fine. Save+Reboot the modem for them to take effect.
But in the separate NAT section, UPNP settings shows the status as disabled.
Don't know the modem type and you haven't posted screenshots so who knows.
[*]Get tested at:
Shields UP!!™. Test your common ports.
[*]Take remedial actions if they are not
stealth.
[*]Since you get scanned by same IPs, scan your computer with
Microsoft's own
Anti-Malware software. It is quite decent and if you have some malware installed it will remove it.
