I can tell you that if you're using ipv4 as your main connection that your subnetting is not correct. Your current default gateway of 220.127.116.11 with subnet of 255.255.224 has a range of 32 ip addresses
18.104.22.168 = network id
22.214.171.124= broadcast address. Your range needs to be between
Changing your ip address is that range will fix your connection.
My other question is why are you not using a private address?
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
Then you also need to check your 6to4 tunnel. Possible even disable it to make sure its setup correctly and not causing any problems. I'm not fluent in IPV6 though so someone else will have to step in if that's the problem.
run this in a command line as an administrator to reset the default IPv6 state
netsh interface ipv6 reset
