Hi Folks,I encounter several problems regarding routing with a vServer host that has mutliple networks.
I have a host which occupies three networks, my guest has IPs only in two of them resulting in the problem, that guest is unable to ping the third network under certain circumstances.
When I try to ping the third network, the packets are emitted with source address from the first activated network (so, the lowest number in the interface directory) - in my case this is an internal maintenance LAN and I get packets that are unroutable. The packets are routed to teh target but are discarded there because they come in via the external NIC (third network) but have a source adderss that belongs to the internal NIC.
I hope anybody understands this description - but I cant describe it better...
The workaround for now is, to setup the IP belonging to the default route of the host as first in the vServer. It also works when I discard all network-routes from the hosts routing table and adress this by source based routing policies.
But I assume that it would be best, when the implementation of vServer network-management hides all routes that are not accessible by the guest.
