>How-To-Repeat:
We use this function to add entry to ipfw table. But we can't repeat the problem on tests.

int ipfw_add(char *ip,int table,int value) {
    ipfw_table_entry ent;
    ent.tbl = table; // table number
    inet_aton(ip,(struct in_addr*)&ent.addr); // ip address
    ent.masklen = 32; // ip mask CIDR
    ent.value = value;
    return do_cmd(IP_FW_TABLE_ADD, &ent, sizeof(ent));
}
