You should insert another rule to block incoming traffic from the internet to port 3124 above
Code:
iptables -A INPUT -p tcp --dport 3124 -j ACCEPT

eg:

Code:
iptables -A INPUT -i eth0 -p tcp --dport 3124 -j DROP
iptables -A INPUT -p tcp --dport 3124 -j ACCEPT

iptables-apply(8)					      System Manager's Manual						 iptables-apply(8)

NAME
iptables-apply - a safer way to update iptables remotely SYNOPSIS
iptables-apply [-hV] [-t timeout] ruleset-file DESCRIPTION
iptables-apply will try to apply a new ruleset (as output by iptables-save/read by iptables-restore) to iptables, then prompt the user whether the changes are okay. If the new ruleset cut the existing connection, the user will not be able to answer affirmatively. In this case, the script rolls back to the previous ruleset after the timeout expired. The timeout can be set with -t. When called as ip6tables-apply, the script will use ip6tables-save/-restore instead. OPTIONS
-t seconds, --timeout seconds Sets the timeout after which the script will roll back to the previous ruleset. -h, --help Display usage information. -V, --version Display version information. SEE ALSO
iptables-restore(8), iptables-save(8), iptables(8). LEGALESE
