My servers main IP is say 204.11.xx.xxx. When I run ifconfig I have a bunch other IPs I've allocated to my server such as 204.11.xx.xxx,204.11.xx.xxx, 204.11.xx.xxx, etc. I don't use these IPs. should I block them with csf? how? I don't want to block anything incoming to my main IP of 204.11.xx.xxx. can I block these other IPs?
ifconfig example:
eno16780032:cp1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 204.15.xxx.xxx netmask 255.255.255.255 broadcast 204.15.xxx.xxx
ether 00:0c:29:3e:25:a1 txqueuelen 1000 (Ethernet)
eno16780032:cp2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 204.15.xxx.xxx netmask 255.255.255.255 broadcast 204.15.xxx.xxx
ether 00:0c:29:3e:25:a1 txqueuelen 1000 (Ethernet)
