Follow-up Comment #3:
Thanks for the info. I've tested it with "PBUF_POOL_BUFSIZE 64" and also got
no connection.
lwIP makes the assumption that all IP/TCP/UDP headers must fit into the first
pbuf. With modern TCP implementations and a pbuf size of 64 bytes, this is
obviously not the case (since many TCP options can make the TCP header quite
big). I guess we'll have to fix that...
As a workaround, you could use "PBUF_POOL_BUFSIZE 128"...
