      Description

      If you deploy your application on UCR in Bridge mode then that service will not be accessible from the agent on which it is deployed using L4LB VIP.

      curl http://11.179.22.252:10000/repo.json

      From tcpdump, looks like IPVS is not picking up the traffic

      tcpdump -n -i any host 11.179.22.252
      tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
      listening on any, link-type LINUX_SLL (Linux cooked), capture size 262144 bytes

      Looks like IPVS doesn't pick the traffic if the real server is local.
