Multiple Consul nodes same WAN address

Hello everyone,

I’m trying to finish a hashistack (consul, nomad, vault) proof of concept for the company I work for and I would like to ask for help about the consul configuration.

Our scenario:
We have a consul server in the cloud communicating with the nodes through WAN. I’m configuring the nodes to advertise the WAN IP. I’ve noticed that with that configuration we can’t deploy more than one node with the same WAN IP (advertised IP).

What would be the best configuration considering that the node wouldn’t be in the same network (availability zone) of the server, and considering that we could have more than one node in the same WAN network?

Thanks a lot.

Luiz Henrique
