Creating a VPS in Proxmox with assigned ips
Can someone help me set this up? I got a Delimiter dedicated server, and have an IP 12.20.86.60 for the server. I asked and got provisioned 12.20.87.62 and 12.20.87.63 as additional ip addresses (on a different subnet). I would like to create two VPSes with each of the provisioned IPs.
Proxmox kernel is loaded.
In /etc/vz/vz.conf, I have set NEIGHBOUR_DEVS=all and rebooted.
In Proxmox, I created a container 101, in routed mode and assigned it 12.20.87.62.
Normally this is all that's required to get the container up and running. However I can neither ping to, or ping an ip out of the container thus created.
On the main server, network config:
# cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto vmbr0
iface vmbr0 inet static
address 12.20.86.60
netmask 255.255.255.192
network 12.20.86.0
broadcast 12.20.86.63
gateway 12.20.86.62
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
auto eth0
iface eth0 inet manual
On the container:
# cat /etc/network/interfaces
# Auto generated lo interface
auto lo
iface lo inet loopback
# Auto generated venet0 interface
auto venet0
iface venet0 inet manual
up ifconfig venet0 up
up ifconfig venet0 127.0.0.2
up route add default dev venet0
down route del default dev venet0
down ifconfig venet0 down
iface venet0 inet6 manual
up route -A inet6 add default dev venet0
down route -A inet6 del default dev venet0
auto venet0:0
iface venet0:0 inet static
address 12.20.87.62
netmask 255.255.255.255
How can I set this up in routed mode?
tracing the route:

As you can see, route stops at the main server.

I believe you need the following iptables rule to route external traffic:
iptables -t nat -A POSTROUTING -s [ip local range] -o eth0 -j SNAT --to [public ip]
e.g.
iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j SNAT --to 123.33.17.52
@EdgeWeb, I have received two failover ips. Does what you posted still apply?
Try adding a route to their gateway
route add 12.20.86.62 dev venet0
route add 0.0.0.0/0 via 12.20.86.62
Not sure that's the correct command, but essentially you need to tell it the gateway is reachable via venet0 (Because it sits outside the devices subnet) and then you can set a route telling i to use the gateway for all other traffic.
this worked for me on an OVH server in the past
@dragon2611 To be set from within the container?
Yep if it's bridged rather than routed.
is it like OVH where you have to register the NIC's mac with them?
I would like to go with routed mode. Hitherto (in ovh and online.net) I'd just add the failover IPs to Proxmox while creating cts and it would simply work. The traceroute shows that the routing till my dedicated server is setup properly. It simply does not route to the containers. I have next to no knowledge regarding network configuration. Could you explain what to type, and where, whether on the server or within the containers (after doing a
vzctl enter?Isnt this possible using routed mode?
Rather difficult. Took me several hours to find a working config but this is because I'm new to proxmox. The key was to use 'pointopoint'. I came with the following:

@Joelgm - PM me the config and the assigned IPs.
