How to configure a redirect rule on the loopback interface

[shuangg]

I need a rules to direct port 80 to port 8080 on the loopback interface, but the rule CSF generated excludes loopback (!lo). Is there a way I can have
iptables -t nat -I OUTPUT -p tcp -o lo --dport 80 -j REDIRECT --to-ports 8080

Found one solution - create / etc / csf/ csfpost. sh and add the command into it.
