vi / etc / sysconfig / iptables
затем добавьте:
-A INPUT -i eth0 -s 100.101.102.103/32 -p tcp -m tcp --dport 22 -m state --state NEW,RELATED,ESTABLISHED -m comment --comment "SSH inbound" -j ACCEPT
-A INPUT -j DROP
-A OUTPUT -o eth0 -p tcp --sport 22 -m state --state RELATED,ESTABLISHED -m comment --comment "SSH outbound" -j ACCEPT
-A OUTPUT -o eth0 -p tcp --dport 22 -m state --state NEW,RELATED,ESTABLISHED -m comment --comment "General SSH outbound" -j ACCEPT
Замените 100.101.102.103 любым нужным IP-адресом
