Why port forward not works?
Francesco Pace last edited by Francesco Pace
I've this configuration on my WDSL connection.
An antenna with DHCP disabled and an Amplifi router connected via LAN with a static ip address:
- Ip Address: 192.168.0.100
- Network mask: 255.255.255.0
- Gateway: 192.168.0.251 (Antenna)
- Primary DNS: 188.8.131.52
I've purchased a static ip address, my purpuse is to expose a simple SSH server of my raspberry in this way:
So, I've configured the antenna port forward:
- Interface: PPP
- Private IP: 192.168.0.100 (the amplifi router)
- Private Port: 222
- Type: TCP
- Source IP/Mask: 0.0.0.0/0
- Public IP/Mask: 0.0.0.0/0
- Public Port: 222
And in the Amplifi router, I've set the port forward:
- IP Address: 192.168.1.102 (My raspberry)
- Source port: 222
- Dest post: 22
- Protocol: TCP
Now, if I execute a nmap command:
nmap -p 222 -sV -P0 <ip>
I always receive:
PORT STATE SERVICE VERSION
If I remove the 222 rule on the antenna, the nmap returns "Closed".
I think that the problem is on the Amplifi that doesn't route the traffic.
How I can solve?
I've request the access to ssh server of my antenna.
When in, I try to connect (always through SSH) to raspberry passing by amplifi router:
- ssh <ip_antenna>
- $ ssh -p 222 192.168.1.100
but I have "Connection timeout".
Same issue if I remove the rule into Port Forward options of Amplifi. Seems that the rule isn't considered.
At the end, with rule or without rule the result is the same.
I suppose that this shows that the antenna Port Forward works and there are some issues with amplifi port forwarding feature.
