# Performing Post Installation Network Configuration

During the installation of the OMT infrastructure, the system created new services providing OMT management and reconfiguration. These services listen on different ports than the OMT installation interface. OMT management listens on port 5443 and reconfiguration on port 443. In this section we will perform network configuration for these ports.

## Get OMT Ingress Service Node Port for Port 5443

To get the ingress service node port for port 5443:

1. Run the following command:
   `kubectl get svc -n core | grep portal-ingress-controller-svc`

Example output:

`portal-ingress-controller-svc NodePort 172.20.26.194 <none> 5443:31704/TCP,5444:32558/TCP 170m`

1. Record the ingress service node port for port 5443 (in the example, 31704) in the AWS worksheet.

Next Step: Create a Target Group for Port 5443
