Maybe, maybe not, your provided rather little information about your
application scenario. Please send information about the Genode
platform you use, init configuration, the log messages, and at best
your source code (snippets). Did you implement a client or server
application?

First, try to find out, if any packet leaves or enters your Genode
network node with Wireshark or a similar tool. Lwip should do DHCP to
discover the network configuration. You could also try to ICMP ping
the Genode node from another node in the network.
