How to Accept SMTP Requests for Subnet Only
how do I allow ip addresses for subnet 192.165.x.x to access my server via SMTP but any other subnet outside of that group is rejected?
I tried the following syntax:
iptables -I INPUT 1 -s 188.8.131.52/16 -d 184.108.40.206 -p tcp --dport 25 --tcp-flags SYN,RST,ACK SYN -j ACCEPT
iptables -A INPUT -d 192.168.17.3 -j REJECT
Will this work?
