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

[zhou yi]

My network does not support dhcp, the router address is 192.168.0.1, my 
computer ip is 192.168.0.128. the lwipcfg_msvc.h is like following:
#define LWIP_PORT_INIT_IPADDR(addr)   IP4_ADDR((addr), 192,168,0,200)
#define LWIP_PORT_INIT_GW(addr)       IP4_ADDR((addr), 192,168,0,128)
#define LWIP_PORT_INIT_NETMASK(addr)  IP4_ADDR((addr), 255,255,255,0)
Is this setting means the httpd server ip is 192.168.0.200? Why I can not 
connect to the Lwip 1.3 httpd server? Thanks.
