Why port forward not works?
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: 18.104.22.168
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.
