SCG leaking docker internal networks
Recently I checked logs from a firewall behind my SCG lives and found some drops of packet originating from a docker internal network. I don't think it should happen. Is this a known bug or something?
The destination address does not resolve in DNS and belongs to Dell ASN 3614.
An example:
INSPECT-OUT forward: in:mgmt out:uplink, connection-state:invalid src-mac 00:50:56:a4:19:c0, proto TCP (ACK,FIN), 172.18.0.2:38100->128.221.236.246:443, len 52No Events found!

Tommydpl,
That doesn't appear to be an issue, the reason being is that you can't contain it to just inside the Appliance so that it's possible for it to go external.
Let me know if this helps.
