Well if you can sacrifice on number of sockets and higer thruput ,it is
possible to do it in that memory constraint.
See lwipopts.h and keep the figures as low as possible . Following are the
tunable parameters

#define MEM_SIZE                1000
#define MEMP_NUM_PBUF           40
#define MEMP_NUM_UDP_PCB        1
#define MEMP_NUM_TCP_PCB        1
#define MEMP_NUM_TCP_PCB_LISTEN  1
#define MEMP_NUM_TCP_SEG       10
#define MEMP_NUM_SYS_TIMEOUT    5
#define PBUF_POOL_SIZE          5
#define PBUF_POOL_BUFSIZE       1500
#define TCP_SND_BUF             2480
#define TCP_WND                 2480
#define ARP_TABLE_SIZE 2
