EVE-NG cannot find an external host

Hello Guys,
I installed the EVE-NG image in my ESXi and all work fine.
However, when I create a network object to connect to an ACS host, I cannot access this host or ping or access by ssh or telnet.
I follow this link
https://www.youtube.com/watch?v=efx-Cr0oGdw to configure external connections, but I only can ping the host from the EVE-NG host. If for example, I ping from the gateway, is not possible.
Can someone help me with this issue?
Regards,
Luis

We do not know your topology, if all the devices in same network example 192.168.1.X/24, they can communicate each other.
If they have different network, you need to have routing in place.
Fix the routing.

Hi R!
First of all, thanks for your answer.
All machines are in the same subnet 10.0.0.0/24, for this reason, I open this case.
For example, if I ping from EVE-NG to IOL ip, I can ping and if from I ping from IOL to EVE-NG host, no problem.
But, if I ping from a host outside EVE-NG host, I cannot. Example, my IOL router have the IP address 10.0.0.2/24, my APIC-EM have the ip address 10.0.0.3/24 and my EVE-NG have the ip address 10.0.0.10/24, I can ping only 10.0.0.10 from my IOL.
All interfaces are in promiscuous mode according to a video posted on EVE-NG channel and don't have firewall rules blocking traffic on this network.

As per your description it should work..where is your default G/W reside, what is the IP address of that ?

My default gateway is a ASR. From EVE-NG, I can ping the GW, but not from IOL.
A question, all machines need stay in a same server?
For example, my APIC-EM and the EVE server need still in a same server to work?

ASR is your DSL or WAN Edge router to Internet- ASR is inside node? ASR can able to ping external IP ?

Not required to be, but as long L3 reachable should be good.
For example, my APIC-EM and the EVE server need still in a same server to work?
APIC-EM can be any where..make sure you have network reachable.

Yes, my ASR have a port in my LAN network. This port is the gateway.

Not required to be, but as long L3 reachable should be good.
But the IOL router is not reachable to my network.

From my apic-EM I cannot reach my IOL router.

Show us your network diagram with IP in it.
