Hello everyone
I successfully create a GenieACS server, and everything works perfectly with local CPEs. They connect, receive parameters, and accept commit commands without issues.
However, I am facing a problem when trying to connect a remote CPE. It fails to connect to the ACS, and I cannot see any logs regarding these attempts on the server.
Environment & Topology:
- GenieACS Version: 1.2.13
- CPE Model: ZTE 670L, Huawei AX2 and
- Remote Scenario: The remote CPE receives an IP via PPPoE and is behind a CGNAT.
- Network Path: The server has a direct route to the CPE subnet.
Troubleshooting steps taken:
- L3 Reachability: The CPE can Ping the GenieACS server IP, and the Server can Ping the CPE.
- L4 Reachability: I performed a TCP connection test from the CPE network to the GenieACS server on port 7547, and it was successful (Port is open).
- Logs: I checked the GenieACS logs, but there are absolutely no records of the remote CPE trying to initiate a session. I only see logs from my local test CPEs.
The Question: Since there is TCP connectivity and no firewall blocking port 7547, is there any specific configuration required for CPEs behind CGNAT or specific routing considerations I might be missing? Why would the server not log the initial handshake attempt?
Any insights would be appreciated!
