작은 행복을 위한 시

기존에 주니퍼 외부 아이피의 80, 443 포트를 내부 서버로 포트포워딩 하고 있었다.

[edit]
root@SRX340# show security nat destination
pool 192_168_2_2_443 {
    address 192.168.2.2/32 port 443;
}
pool 192_168_2_2_80 {
    address 192.168.2.2/32 port 80;
}
rule-set nsw_destnat {
    from zone Internet;
    rule 0_Web_Server--DMZ_443 {
        match {
            source-address 0.0.0.0/0;
            destination-address 0.0.0.0/0;
            destination-port {
                443;
            }
        }
        then {
            destination-nat {
                pool {
                    192_168_2_2_443;
                }
            }
        }
    }
    rule 0_Web_Server--DMZ_80 {
        match {
            source-address 0.0.0.0/0;
            destination-address 0.0.0.0/0;
            destination-port {
                80;
            }
        }
        then {
            destination-nat {
                pool {
                    192_168_2_2_80;
                }
            }
        }
    }
}

이것을

80->81

443-> 444

로 변경하였다.

방법을 얘기하자면 변경하려고 하는 포트를 set 명령으로 추가하고 기존 포트를 delete 명령으로 삭제해 주면된다.
