We have a Linux box, that is supposed to act as a shaper. For this, there are several 802.1q vlans transported to one of the interfaces. So the setup is something like this: ------------------- - Cisco Router - ------------------- /-------/ \-----------\ upstream | | client vlans connection | | \--- Gi1 - Linux Box - Gi2 ---/ Gi1 is an upstream connection, Gi2 holds several 802.1q vlans. This already works with one vlan transported to it. However, when i try to add another vlan and i try to send icmp packets from one side to the other, arp relationships are established, however only _some_ of the packets sent get a reply from the other side. Of course, testing was done with all qdiscs removed. STP is disabled on the bridge, so is rp_filter. Does anybody have any idea what's going on? Just keep in mind that there already is a connection that works without problems on the same machine. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
