iptable 설정, 혹시 문제 있을까요?

제가 봤을때에는 전혀 문제 없는데

localhost는 서비스가 telnet으로 smtp와 pop3는 접속이 됩니다.

-L 해서 정책이 들어가 있는 부분은

Chain INPUT (policy ACCEPT)
target     prot opt source               destination        
RH-Firewall-1-INPUT  all  --  anywhere             anywhere           

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination        
RH-Firewall-1-INPUT  all  --  anywhere             anywhere           

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination        

Chain RH-Firewall-1-INPUT (2 references)
target     prot opt source               destination        
ACCEPT     all  --  anywhere             anywhere           
ACCEPT     icmp --  anywhere             anywhere            icmp any
ACCEPT     ipv6-crypt--  anywhere             anywhere           
ACCEPT     ipv6-auth--  anywhere             anywhere           
ACCEPT     udp  --  anywhere             224.0.0.251         udp dpt:5353
ACCEPT     udp  --  anywhere             anywhere            udp dpt:ipp
ACCEPT     tcp  --  anywhere             anywhere            tcp dpt:ipp
ACCEPT     all  --  anywhere             anywhere            state RELATED,ESTABLISHED
ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:smtp
ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:pop3
ACCEPT     tcp  --  anywhere             anywhere            state NEW tcp dpt:imap
REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited

와 같습니다.

아 이거 죽겠네요 하루 죙일 ㅠㅠ

ssh는 첨에 안되다가 iptables restart 하니 잘되는데 나머지 smtp와 pop3는 되다 안되니 죽겠습니다.

아웃룩에서 메일 긁는 건 아까는 됐었는데

A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 110 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 143 -j ACCEPT

이 부분의 순서를 바꾸니 또 안되네요

이젠 ssh 밖에 안되고 나머지는 로컬에서만 telnet으로 확인됩니다 ㅠㅠ


머가 문제 일까요??
