Am running IPFW on FBSD-4.8p14 For almost a year (or more), one of my servers has been hammered by redalert.com, a service to which I do not subscribe. My efforts to get them to stop has gone ignored. Every night, the server is peppered with their "taps". Thus, it's time to use a firewall rule to stop it. The problem is that they use a broad range of source IPs. The list I show here is only for the past 4 days. I don't want to block any innocent IPs and wondered how I could best create a rule(s) to stop the 38 IPs below without 38 individual lines in the rules...?? Appreciate help! Thanks! 209.102.202.131 209.102.202.132 209.102.202.133 209.102.202.134 209.102.202.135 209.102.202.136 209.102.202.137 209.102.202.151 209.102.202.152 209.102.202.153 209.102.202.154 209.102.202.155 209.102.202.156 209.102.202.157 209.102.202.165 65.194.51.131 65.194.51.132 65.194.51.133 65.194.51.134 65.194.51.135 65.194.51.136 65.194.51.137 65.194.51.151 65.194.51.152 65.194.51.153 65.194.51.154 65.194.51.155 65.194.51.156 65.194.51.157 65.194.51.165 66.226.213.131 66.226.213.132 66.226.213.133 66.226.213.134 66.226.213.135 66.226.213.136 66.226.213.137 66.226.213.165 Best regards, Jack L.
