Good morning, all, and happy holidays!
I was experimenting with the security settings on a 6102 - remotely. This device has the most up-to-date firmware available, with the exception of the very recent security release. I was adding rules to the Dynamic Defense list. I created a rule blocking access on ports 20001-65535 from any IP. I added a whitelist rule for the VoIP server, but didn’t think about doing so for my office IP address or the local LAN.
I could access the device remotely as my office IP is whitelisted on the router, and port 8089 forwards to the UCM. Or, I could connect to the router by VPN and then access the device as if I was on the local LAN.
Neither of those paths work any more. I didn’t expect this as I thought the UCM was communicating on port 8089 for configuration changes, and that port was not in the range I specified.
Unfortunately this device is an hour away from my office. I’m afraid that even if I go there, I will be unable to access the device even on the local LAN. I’m afraid that I’m looking at a factory reset and then restore a backup.
Can I access the device locally through its LAN port?
The device appears to be functioning - or at least I can see that it is connected to the VoIP servers.
Any ideas would be most welcome.
