Hello!
I using this template for oldest project with managed routing agent.
apiVersion: networking.doks.digitalocean.com/v1alpha1
kind: Route
metadata:
name: nat-gateway-route
spec:
destinations:
- 0.0.0.0/0
gateways:
- 1.2.3.4
I tried this in fresh cluster, and this template broke the ingress traffic.
I need to access a service with a fixed IP address. Unfortunately, they don’t tell me exactly what IP addresses their service can be accessed from. Is there a way to route all traffic to the nat gateway like before?
thanks!

I changed the load balancer type from REGIONAL_NETWORK to REGIONAL. That’s solved my problem.
Hi there,
As far as I understand, you should still be able to route all outbound traffic through a specific gateway using the routing agent by setting 0.0.0.0/0 as the destination, but there are a few things to keep in mind.
If your DOKS cluster uses VPC-native networking, this setup should work fine and let you send all egress traffic through your NAT gateway. However, on older clusters or ones using Network Load Balancers for ingress, overriding the default route can break ingress routing. In those cases, you can use a nodeSelector in your route definition to exclude ingress nodes from the default route override.
Here’s the full guide from the docs that walks through this setup: https://docs.digitalocean.com/products/kubernetes/how-to/use-routing-agent/
If you’re not sure whether your cluster supports this configuration, I’d suggest reaching out to support so they can confirm and make sure everything’s set up safely: https://cloudsupport.digitalocean.com/
