Hi Kieran,
thank you for an idea with additional route to a specific IP address. I will
try this.
Thank you.

without routing (using of gateway IP address) ?
Which API are you using? It might be possible with a raw socket (i.e. a
socket of type raw, not the confusingly named lwIP raw API!) You would be
responsible for forming the UDP header etc, but I think this would be worth
a try. All normal data sent via lwIP sockets at the TCP and UDP level would
be subject to IP routing, and we don't support any of the socket options or
flags that would allow you to bypass this.
Another alternative, if you know the address you want to send to to a
specific IP address, you could insert a route for that exact address, and so
get the result you need.
