[resolved] disable anti flood

[greg]

I've just installed OPNSense; it's working ok, I can have traffic in/out, but when trying to use a sustained stream such as rtmp, it stops after a few kB. If I disable the firewall, the stream goes on, so I guess there is some kind of flood prevention enabled. Is there a way to disable it? Thanks in advance

Hey Greg,

TCP streaming protocols can have a negative effect on state tracking. You can see your traffic being blocked by the default rule in the firewall logs probably...

If that is the case, you can add a floating rule for your RTMP traffic, go to the advanced section of the rule and  change state tracking to either sloppy or none, whatever works best.


Cheers,
Franco

Sweet! you nailed it I disabled the stateful inspection and it's working
Now I just have to install it instead of running the live usb
Thanks a lot!

So RTMP is working, then I activated the DHCP for mobile devices to use OPN as the gateway. Now the symptoms are:

- web is erratic, mostly working, sometimes timeout
- speedtest gives ping ok, bandwidth down ok, bandwith up = 0.00

(as for the original problem, if I disable FW or use the cable modem as GW, things are good)

Following your advice I created a FW rule to disable stateful inspection ; I also tried to enable NAT. Nothing...

Any idea?

Thanks in advance
