I am running a streaming server on a node, on the LAN. I want to allow access to it from the Internet. I added a DNAT to forward the specific port it uses to the local IP of the node that the streaming server is running on. I unticked the box for it to automatically create a firewall rule so I could create my own. It seems to be working but I see a lot of dropped packets for the port I have specified in the DNAT and Firewall rules. However, the dropped packets reference the public IP address, not the private address that I specified in the rules.
Web protection is disabled but the WAF is enabled. Only ports 80 and 443 are used in the WAF.
Below are my rules:
DNAT:
Traffic from: ANY
Using service: TCP port 6020
Going to: External WAN address (7.7.7.7, fictitious)
Change the destination to: 192.168.0.2 (Local IP of node running the streaming server)
Firewall rule #1:
Internal (Network) using port 6020 to ANY
Firewall rule #2:
ANY using port 6020 to 192.168.0.2
The dropped packets in the Firewall log are as follows:
10:07:45 Default DROP TCP 5.5.5.5:6223 -> 7.7.7.7:6020
5.5.5.5 being the fictiious public IP of my mobile phone and 7.7.7.7 being the fictitious public IP of my gateway.
Why are these packets being dropped? I'm having streaming issues but I do not know if it's related to these dropped packets or the streaming server and/or app.
Didn't see anything in the IPS log.
