They are even documented in opt.h:

/**
 * IP_FORWARD==1: Enables the ability to forward IP packets across network
 * interfaces. If you are going to run lwIP on a device with only one network
 * interface, define this to 0.
 */
#ifndef IP_FORWARD
#define IP_FORWARD                      0
#endif

/**
 * IP_OPTIONS_ALLOWED: Defines the behavior for IP options.
 *      IP_OPTIONS_ALLOWED==0: All packets with IP options are dropped.
 *      IP_OPTIONS_ALLOWED==1: IP options are allowed (but not parsed).
 */
#ifndef IP_OPTIONS_ALLOWED
#define IP_OPTIONS_ALLOWED              1
#endif
