Default drop on port 8000 (online radio)

Alone among the logs, the Firewall Live Log presents abbreviated information in a format easier to read quickly.  Usually, you can't troubleshoot without looking at the corresponding line from the full Firewall log file.  Please post the line corresponding to the one above.  Also, confirm that your configuration doesn't violate #3 or #4 in Rulz.

I have the following rule for allowing port 8000. But remember my network knowledge is limited.

No group, position 3, internal network 192.168.2.0/24, services TCP, destination port 8000,source port 1:65535, allow. Destination is external network. My only internet connection is mobile broadband modem (4G modem). Is this rule ok? Still getting dafault drop.

Thanks for your help.

I've corrected my post above by adding "Internet" to the traffic selector. Your destination was incorrect.

Cheers - Bob

I choose internet ipv4 for destination. No more default drop. Here is the live log.

And the line from full firewall log.

Still not working. The error in VLC player is your input can't be opened:
VLC is unable to open the MRL 'http://93.103.13.156:8000/'. Check the log for details.

Any luck with #1 in community.sophos.com/.../22065

Well, if VLC has it's own logs what do they say? Maybe they'll be verbose enough to give you an indicator on what it's trying to do. Take a pcap on your client and see what traffic doesn't look right.

I tried to connect this pc to a home router and VLC player is playing without problems.
Here are the logs from VLC player connected on Sophos UTM dedicated pc.

Hope that this is useful.

Does seem to be packet drop related then. So, you can't see any more drops in the Firewall log? Can you look at the IPS logs to see if any other packets are being dropped? Or, create an exception in IPS for that destination address.

I've just tried this on my Mac (Good tunes on that station by the way, got a bit of Wham on right now) and it works via my test UTM

Anyway, it does call HTTP as well so are you using Web Filtering? If so, create an exception under Filtering Options for that destination IP as well (May as well skip everything for this test)

If that doesn't work, I'm pretty stumped. As a last resort, briefly open up your Firewall with a Any --> Any --> Any rule. If that then allows the station to play correctly then we can revert back to looking at the Firewall rules.

As i said before my networking knowledge is limited, but all that was needed for a VLC player to start playing this online radio was to open port 8000 and masquerading rule. Now its working!

Ah okay. Yeah it was probably the masquerading rule. Normally the LAN to WAN Masq covers Any service.

Glad you got it working.
