Hashicorp consul FQDN

Question

1. I have a cluster of VM (vmWare vCloude) with consul server installed on one of them.
2. communication between VM is done ONLY view internal network IP. using ExternalIP is blocked. so consul agents installed on other VM are getting the internal IP as advertised address .
3. I created a few Microservices using k8s that is installed on VM outside the cluster. I can communicate with the cluster ONLY with the ExternalIP.

problem: consul is returning an advertised address from the VM and it can only be either, internal or external IP. if I choose the internalIP then I cannot use it from outside the cluster and if I use the externalIP, then all agents installed within the cluster will not be able to communicate. I did not find a why of configuring the advertised address with FQDN.

Did anyone faced this issue or have a solution for it? Thank you, Lior
