Hi, I am trying to apply some QoS for RTSP traffic forwarded by an OpenWRT gateway (Attitude Adjustment + patches). The RTSP helper is loaded and succesfully expects the incoming streams, which arrive at the client in the NAT'ed lan. Multiwan is also active, this is using part of the marking bits (i.e. 0xF0000000 ) to select the appropriate routing table. In this product, interface drivers sort outgoing frames in different queues based on part of the marking bits (i.e. 0x0F000000). Netfilter rules are present in the forwarding chain to mark streams destined at tcp port 554 with specific qos value (i.e 0x08000000). This mark is saved as connmark at the end of the forwarding chain, and restored at the start. If after restore, the mark is still 0, only then all qos rules are being evaluated. When RTSP helper succesfully predicts incoming streams, these childs automatically inherit the connection mark, and as such will be marked with the same mwan and qos bits as the parent connection. For mwan this is ok, but for qos a different (higher) value would be prefered (i.e. 0x0A000000). Ideally, the child streams should be assigned a specified connmark value when RTSP helper is predicting them. A generic solution that would be applicable to parent-child connections handled by other helpers would be nice :-) So ... what are my options ? -- Thierry -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
