I think that needs to be 'htonl()'.

It'll work of course, but INADDR_PFSYNC_GROUP is in host byte order, and preq.pfsyncr_syncpeer.s_addr is in network order, so you want to go from host to network order, and not the other way around.

Oh, my mistake. I saw the definition and read it as a byte array, ignoring the leading (in_addr_t)

#define INADDR_PFSYNC_GROUP     ((in_addr_t)0xe00000f0) /* 224.0.0.240 */
