Firewall problem, big problem
I spotted a big problem in the firewall ispconfig3, let me explain:
- I installed the server, I installed ispconfig3, I set it up after I enabled the firewall
- I reboot the system, it works
- After I created a client, client's website and FTP
- When I want to connect to FTP client's that does not work, i get this message in flashfxp :
- I did a reboot, it does not work, the server is down
the server ping internally but not externally. Now the only solution is to restore everything
you know why this problem? any fix for that ? :(
I don't know flashfxp but it seems to be an (s)FTP client. The FTP protocol makes use of port 21, while SSH makes use of port 22.
The error you see probably means that you mix up SSH with FTP.
Please use port 21 for your FTP connections and 22 for SSH.
ok thx, it's work ^^
but now i have a big problem :
How is your server coŽnnected to the internet? Do you use a external router?
The ispconfig firewall is for servers that use external routers or are in a datacenter, you can not use the firewall if the server itself uses a software router and is the gateway for other devices on the network as this will cause a conflict in iptables rules.
To fix this if your server is also the network router of your network, simply stop the firewall with its script in /etc/init.d
I do not know, I have a dedicated server at ovh.com ^^
I found that causes the problem, do not select "Network Settings" in server config if the firewall is enabled
Now everything works
