Unable to create private network GRE/VxLAN

mavoff

Hi,

I'm simply unable to successfully create a GRE network. I have XO from sources up to date, port 4460/tcp (&udp in the meanwhile) on all hosts, already restarted the sdn-controller, I always get the error:

sdnController.createPrivateNetwork
{
  "poolIds": [
    "58193dd3-b784-1c3d-1dc7-0143b02feb7c"
  ],
  "pifIds": [
    "f95582c0-f1f5-bce3-7abf-fe247ac3bd44"
  ],
  "name": "DMZ",
  "description": "",
  "encapsulation": "gre",
  "encrypted": true,
  "mtu": 1400,
  "preferredCenterId": "3301ab0a-0a49-4cf3-a430-5e062b669c55"
}
{
  "errno": -113,
  "code": "EHOSTUNREACH",
  "syscall": "connect",
  "address": "192.0.20.1",
  "port": 6640,
  "message": "connect EHOSTUNREACH 192.0.20.1:6640",
  "name": "Error",
  "stack": "Error: connect EHOSTUNREACH 192.0.20.1:6640
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1161:16)
    at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17)"
}

however if I netcat from the xo server to the hosts port 6640 I always connect.

Although the most common IP is the master (and the one I select as preferred center) I've gotten most of the hosts in the pool.

The logs overview is like:
