Question: Advertised Address is not advertised back to Client

[clavinjune]

I am using Kafka Proxy to proxying 3 nodes of kraft for jaeger collector

here's my configuration:

- --bootstrap-server-mapping=kraft-0.ns.svc.cluster.local:9092,0.0.0.0:30001,foo.com:30001
- --bootstrap-server-mapping=kraft-1.ns.svc.cluster.local:9092,0.0.0.0:30002,foo.com:30002
- --bootstrap-server-mapping=kraft-2.ns.svc.cluster.local:9092,0.0.0.0:30003,foo.com:30003

the kafka producer URL used by my jaeger collector is foo.com:30001,foo.com:30002,foo.com:30003

when the jaeger collector is connected to the proxy, it returns

"dial tcp 0.0.0.0:39081: connect: connection refused"

If I used kcat to check the topic

kcat -b kafka-proxy.ns.svc.cluster.local:30001 -L
Metadata for all topics (from broker -1: kafka-proxy.ns.svc.cluster.local:30001/bootstrap):
 3 brokers:
  broker 0 at 0.0.0.0:46723 (controller)
  broker 1 at 0.0.0.0:39081
  broker 2 at 0.0.0.0:37183

it seems the adv addressed (foo.com) is not advertised back

any wrong configuration that I did? thank you!
