Help Specifying IP Range for Windows Firewall

[CharlieB]

Hello, I am confused on how to specify the "From" and "To" addresses to block IP addresses from even connecting to my server. I'm getting a bunch of bogus SMTP traffic that I would rather never even got in..

I tried to use: From: 114.36.0.0 To: 114.42.255.255

But I obviously don't know what I'm doing as this isn't blocking them.

Thanks..

Here are a few of the addresses:

114.36.6.110
114.42.16.211
114.36.13.108
114.36.89.156
114.36.8.105
114.36.3.190
114.36.88.172
114.42.13.132
114.42.21.86
114.42.8.95
114.42.4.78
114.42.13.242
114.42.11.193

Figures, all those IP addresses are from Taiwan. My router is inundated with speer phishing attacks from China and Taiwan.

If you arent expecting any mail from China you can safely add 114.0.0.0/8 to the firewall rule If you want to deny all of the asia pacific area:
