If the Pod (10.244.0.1) is matched by the egress policy and the destination address of the traffic matches the destCIDR, the traffic is expected to be dropped in the current version.

apiVersion: egressgateway.spidernet.io/v1
kind: EgressGatewayPolicy
metadata:
  name: "policy"
spec:
  appliedTo:
    podSelector:
      matchLabels:
        app: "shopping"
  destCIDR: 
   - "1.1.1.1/32"

from egressgateway.

If the source IP of the reply package isn't LB IP when it exits cluster, the package will be dropped:

from egressgateway.

Their solution is to create a SNAT rule in the Node that converts the source address to the LB IP
