[Starlingx-discuss] How to access Virtualized central cloud from outside the Host

[Rai, Ankush]

Hi,

I have installed the central cloud (All in one Duplex) in a virtualized environment. But not sure what NAT rules are required, to access it from outside the Host machine.

  *   Below is my deployment.

  *   Starlingx is installed.

system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
| 2  | controller-1 | controller  | unlocked       | enabled     | available    |
+----+--------------+-------------+----------------+-------------+--------------+




  *   Packets are reaching to the Host machine
listening on ens1, link-type EN10MB (Ethernet), capture size 262144 bytes
11:35:56.144807 IP 14.141.56.230.61002 > 172.31.21.86.8080: Flags [S], seq 1632511605, win 65280, options [mss 1360,nop,wscale 8,nop,nop,sackOK], length 0

  *   I have tried below rules.

iptables -t nat -I PREROUTING  -i ens1 -p tcp --dport 8080 -j DNAT  --to-destination 10.10.10.2:8080

iptables -A FORWARD -j ACCEPT


iptables -t nat -I POSTROUTING -s 10.10.11.0/24 -o enp125s0 -j MASQUERADE

iptables -t nat -I POSTROUTING -s 10.10.10.0/24 -o ens1 -j MASQUERADE





  *   Ipv4 forwarding is enabled on the host and from Host I can reach the controllers.

But still could not see packet reaching to the controller. Any suggestion would be very helpful.

Thanks,
Ankush
