SIP issle with .99 Beta for Flint 3

[dervari]

I’m seeing some strange issues with port forwarding on the Flint 3.

• UDP/5060 is forwarded from WAN to LAN 10.1.1.1
• Tried with FW rule in place and without
• nmap from my Oracle Cloud shows TCP/5060 open and UDP/5060 Open/Filtered
  • No forwarding rule for TCP/5060 exists.
  • Flint 3 appears to be listening on this port.
• TCPDUMP on 10.1.1.1 shows no inbound traffic
• Forwarding 22/TCP WAN→LAN works fine
• Tried with ALG en/disabled
• Enabling DMZ to 10.1.1.1 seems to work as nmap shows UDP/5060 open

Any ideas on why port forwarding appears to be not working? Anyone else having this issue?

Hi

We have tested this locally on a Flint 3 running firmware v4.8.99 and have not been able to reproduce the issue—the port forwarding rules are working normally on our side.

Please help to check the following:

1. Provide a screenshot of your current Network > Port Forwarding configuration.
2. SSH into router and run the following command to verify whether the corresponding rules have been created:

nft list ruleset | grep 5060

Went back to the latest mainline release (non-beta) and all appears to be working now!
