In IP FILTER option I am trying to stop a WAN IP address. But every day when this dynamic IP changed the blocking become void. Is there a way to enter IP range like for an example 126.96.36.199 - 188.8.131.52
More aboutblock address
Is there a place to enter the subnet mask? 184.108.40.206 255.255.0.0 would block that entire network (the 94.200.x.x network).
Any decent firewall will let your use ranges or masks. I know Win7 supports this.
