Dear all,
Dear support and users:
Sorry to trouble you! I configure the shorewall firewall to forward ftp and ssh port to another server, but failed. Can you help me check?
I cannot login both SSH 2222 and ftp!
Below is my environment: (attachment is shorewall dump)
1. Gateway (FC6)
1.1) eth0: lan static IP: 192.168.1.20
1.2) eth1: external public static IP: 113.89.142.80
2.3) Shorewall-3.2.8 is running
2. FTP Server: (Centos63, iptables and selinux are off)
2.1) eth0: lan static IP: 192.168.1.231
2.2) Open SSH port 22 and FTP port 20, 21 already (tested)
2.3) vsftp.conf : use default settings and it works for internal users
3. I want to forward internet access FTP and SSH to FTP Server:
3.1) 113.89.142.80: 20 -> 192.168.1.231:20 udp (FTP)
3.2) 113.89.142.80: 21 -> 192.168.1.231:21 tcp (FTP)
3.3) 113.89.142.80: 2222 -> 192.168.1.231:22 tcp (SSH)
4. Shorewall settings:

do you know what's wrong?
Thanks and best regards!
