Re: [lwip-users] How to set the lwip configuration under win32

[address@hidden]

Since you didn't use DHCP and some pings succeed, I don't think the 
port-specific configuration is your problem. Maybe some other 
configuration options (look at lwipopts.h) are set so low that you run 
out of memory somewhere? Or you have a routing problem? I would take a 
look at 'lwip_stats' in the debugger to see if you ran out of memory and 
if not take a look at the actual network traffic using wireshark.
