RE: [lwip-users] Listen on more then one port with lwIP

[Muhamad Ikhwan Ismail]

Hi,

It would help the developer answer your question, if you explain what do you mean by it does not work
e.g. where it blocks, you are getting no data or something like that. You should also search the mailing list
for previous posts, someone might have asked the same q.

You might want to info them also of your port and version.

Greetings
Ikhwan
