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.
